What are the reasons for a breastfed baby not gaining weight?

An International Board Certified Lactation Consultant (IBCLC) is the ideal breastfeeding specialist to help you discover the Reasons for Low Milk Supply.

#3 One thing leads to another

Once a baby is underweight they can become very sleepy and not very interested in feeding. Or they may seem hungry, simply quickly fall comatose at the breast instead of actively feeding.

Is my baby gaining enough weight?

If your baby is gainingsomeweight, yous may wonder if y'all actually practise need to be worried or whether it is inside normal limits. It may help to read Is My Baby Getting Enough Milk? and Understanding Your Baby's Weight Chart. The World Wellness Organisation (WHO) weight charts evidence the expected growth curves seen in healthy breastfed babies. In that location are separate charts for boys and girls since they grow slightly differently. You can download these charts and plot your baby's weight yourself (weight for age 0-half-dozen months GIRLS & BOYS) so you tin see how your babe'south growth compares. In that location are as well growth apps that tin tape baby's weight on your phone that use the aforementioned charts.

Normal gain

The WHO charts show that weight gains of 30g­­‑40g per solar day in the start 3 months are to be expected when a baby is growing well. This slows down between 3­­‑vi months to an average gain of 20g per 24-hour interval.

Crossing centiles?

If your baby is gaining less than around 30g­­‑40g per day in the first iii months or less than nigh 20g per day betwixt 3­­‑6 months, their growth bend may start to drift away from their weight-for-age curve. It may brainstorm crossing the pre-drawn centile lines in a downward direction. See Understanding Your Baby's Weight Chart for more information on centiles and examples of curves that show faltering weight gain.

Crossing centile lines on the WHO chart may just be a sign that your baby's birth weight was inflated, perhaps y'all were on an IV drip during labour. Or information technology may mean that your babe is destined to be tiny and petite just like his parents, or long and lean like Uncle Larry. Or it may be because he has been poorly recently. However this tin't be established past someone who has never seen y'all and your baby on Dr Google or in a Facebook thread. If your breastfed baby is consistently not gaining weight (or negligible weight) consider seeking the assist of an IBCLC lactation consultant to work with you and your health professionals; sooner rather than later. There is no advantage to waiting to see if the problem disappears.

Hungry or satisfied?

In addition to monitoring weight gain, information technology is useful to be aware of some typical characteristics of both an underweight infant and ane who is getting enough milk:

  • The hungry/underweight baby.A infant who has not had enough milk may be tense, with his artillery bent at the elbow and held close to his torso. He may fall asleep with his hands in tight fists and wait worried with a frown on his face up. A hungry infant may seem fussy and desire to stay at the breast for long periods which may exist mistaken for breastfeeding "continuously" but really he is not actively sucking or swallowing milk. Fussy behaviour or difficulty sleeping might also be attributed to colic, reflux, silent reflux or intolerance to female parent'south diet instead of hunger. Alternatively a hungry baby may sleep a lot and be mistaken for a "skillful baby". A very underweight babe can have loose pare and facial features that look like a niggling quondam man and he may have infrequent wet or dingy nappies. Signs of dehydration include dry lips and mouth, drowsiness, and dark, concentrated urine.i
  • The infant who is full.When your infant has had enough milk or is full to satiety he will normally autumn asleep and allow go of the breast on his own after a menstruum of active sucking and swallowing. He will have relaxed hands and probably a 'milk drunk' satisfied expression. He volition have enough of wet and dirty nappies each day and proficient weight gain (meet Is My Baby Getting Enough Milk? for more information).

Adjacent steps

In an ideal scenario the health visitor or midwife volition pick upward on 18-carat poor proceeds at the outset sign of a trouble and refer the female parent to a breastfeeding specialist to protect breastfeeding and ensure the babe gets more than milk. A close center volition exist kept on the baby's weight gain by weighing regularly (e.g. weekly or more often). An IBCLC lactation consultant will usually take a total medical history, study the baby's weight chart, scout a breastfeed from first to stop and put a program in identify to increase baby'southward intake of milk to become them back on rail.

Stride one: feed the baby

If a baby is considerably underweight it may accept time to build his mother'southward milk supply and formula may be needed at get-go unless donor milk is bachelor or unless the baby is of an age when solid foods tin fill up the gap. Mothers who can't access donor milk and are reluctant to utilise formula may need gentle counselling to understand that the priority is to rebuild their infant's bodyweight and energy levels; they need more than food. It can help the mother to recollect of formula every bit a necessary medicine to supplement direct breastfeeding.

If a mother can pump plenty breast milk then that tin can and should exist used as the supplement instead. Just nosotros have to assume that for whatever reason, the baby is not able to get enough milk from the breast themselves and the first rule is to go the baby fed… to satiety (i.e. until they are total).

How to supplement the underweight baby

Top-up supplements tin can be given to a baby past an open cup, by supplementing at the chest (when a pocket-sized tube delivers supplement alongside the nipple (come across pictures below) or by finger-feeding (baby suckles a finger with a feeding tube fastened). A bottle tin likewise exist used to give supplements after each breastfeed and may be a good choice for the underweight infant who keeps falling asleep without feeding well. Although bottles tin can sometimes crusade problems breastfeeding for some babies due to nipple preference or confusion, these Tips to Canteen Feed a Breastfed Infant can assistance. Topping upwards by bottle before a breastfeed is some other option. Run across our care programme: Supplementing an Underweight Baby for much more data. With more than milk inside him, your baby will have more energy to breastfeed finer.

Step ii: build mother'southward milk supply

With baby'due south calorific needs met in the brusque-term, work can brainstorm on maximising a mother's milk supply. Afterward breastfeeding from both breasts for a combined total of around 20-30 minutes, fourth dimension spent pumping or hand expressing volition stimulate the breasts more finer than continuing to breastfeed for hours at a time with a baby who isn't really drinking (and isn't gaining weight). Run into How to Make More Breast Milk and How to Increase Milk Supply When Pumping for ideas to maximise your supply.

Catch up growth

If your babe has been short on calories for some fourth dimension, in that location volition usually be skillful grab upwardly growth once they are getting more milk. Gains of at least 56g per twenty-four hoursii tin can be expected for several days or longer. Weight gains up to 120g per day could be possible 3. Your infant may govery interested in feeding and may take more than and more than supplement when their ambition returns and they showtime to catch up.

All children with failure to thrive need additional calories for take hold of-upwards growth (typically 150 percentage of the caloric requirement for their expected, not actual, weight).

Unless the infant has an underlying medical problem, failure to brainstorm catch-upwardly weight gain means insufficient supplement is being given.

Lookout out for poor communication

Hopefully your health professional will be very knowledgable about breastfeeding. Unfortunately they may not be or you may come across poor advice from elsewhere. Advice to go along to one chest "to reach the hind milk" will generallyreduce your milk supply (read more here and here). Advice to feed more often or for a certain number of minutes isn't helpful if that baby isn't very good at feeding, why spend more than time doing something that already doesn't work? Alternatively the communication yous hear may be to supplement with formula—without addressing the underlying breastfeeding problems. Keeping to one breast or suggesting formula instead of breastfeeding without actively trying to increment a mother's milk can undermine breastfeeding and crusade early weaning.

Seek a second opinion

At the other extreme, a wellness professional or the mother herself may be so pro-breastfeeding that she is overly optimistic nearly the low weight gain picking up soon all on its own. They may continue to monitor the situation without taking activeness when weight gain is as depression as 12g per day or even less. They may think that if baby is post-obit his own curve he is OK, even if it is well below the chart. If this is the case for you lot, asking for a second stance from a paediatrician will ensure that your baby is fit and healthy and there are no health concerns. Afterward all a few good for you babies volition be on the 1st centile. If not, an IBCLC can assist you make a tailor made programme to increase your milk supply and go your infant taking more than calories.

NICE guidelines

Dainty (National Found for Health and Care Excellence) guidelines recommend further medical assessment for unpleasing growth if a baby'south weight falls beyond two or more centile spaces if birthweight was between the ninth and 91st centiles and a fall across one or more centile spaces if they were born below the 9th centile.4

Avoid Dr Google and Nurse Facebook

When a mother badly wants to breastfeed, and is worried about her babe, she may look to search engines on the internet and social media platforms. She may notice breastfeeding forums where mothers reassure her that their babies didn't gain much weight either but they were fine, and that she is doing great, and that breastfeeding is the all-time thing for her infant. They may tell her "carry on hun" or another favourite "it sounds just similar a tongue-tie". However these cheer leaders often don't enquire any important questions; they can't see the baby'south weight nautical chart; they are not trained breastfeeding specialists. Following this kind of communication may lull the mother into a false sense of security while her infant continues to fail to thrive and her milk supply gets less and less.

A note on natural language-tie

Although information technology may be the latest trend on Facebook, not everything that goes wrong in the breastfeeding world is nearly tongue-tie. Many low weight gain babies will prove poor tongue activity because they are very tense and very hungry. Yeah, there may exist a tight frenulum (the membrane under the tongue), but let your IBCLC or experienced tongue tie practitioner advise you, not Dr Google. Dividing a natural language tie and so expecting everything to turn out great equally if by magic is lulling you into a false expectation. If a babe is 25-xxx% beneath their expected weight for age, your milk supply is likely already compromised and waiting around for the magic on the tenuous footing "it can take 2‑3 weeks to piece of work out how to use their tongue" tin can mean 2‑3 more than weeks of slipping behind in calories.

Prevention is ameliorate than cure

Unfortunately IBCLCs do come across babies 30% below their expected weight in the community. At this point in that location may already be a referral to a paediatrician. Social services may even take been called. And everyone will be worried. By getting the right help as before long every bit at that place are early concerns, this upsetting situation tin can hopefully be avoided.

The consequences of inadequate intake of breast milk range from hyperbilirubinemia, baby hunger, and slow weight gain to life threatening, and even fatal, dehydration and starvation.

Summary

A babe who is very under weight may not exist able to breastfeed effectively and his mother's milk supply may be very low. An action program involves increasing a baby's calorie intake with supplements, building his mother'south milk supply and finding the underlying reason for low weight gain. At that place are lots of ideas on this website for increasing your milk supply to become y'all started, only for specialist aid consult an IBCLC lactation consultant alongside your doctors. Cull one who can spend the time needed to take a full history, make an private intendance plan and liaise with your wellness care professionals.
