✨Weight gain expectations when weight is faltering.✨
I am seeing far too many families whose babies have met faltering weight criteria at multiple points.
• first few days of life lost >10% of birth weight
• not back to birth weight by 3 weeks (or more)
•falling through centiles
✨Babies are expected to double their birth weight by 4 months and triple it by a year.
IBCLC work often involves optimising milk transfer at the breast and/ or supplementing while addressing root cause issues.
I am a strong advocate of holistic support, I absolutely love seeing families early enough to nip issues in the bud. However there is nothing more frustrating than families being falsely reassured, feeding plans stopped prematurely and being told baby is finding their own line etc.
⚠️Consistently gaining below expected weight will result in a baby’s weight continuing to falter.
The main cause of gaining below expected is that baby is not taking enough milk on board. The why is important to find out so that any plan is tailored to you and your baby. Feeding plans for faltering weight should result in gains in excess of expected.
✨If a baby is not used to larger volumes, they may struggle to take what’s needed for the first 24 hours or so. Then tend to develop a ferocious appetite while they catch up to their expected weight for age.
✨Gains > 56g a day are common while baby replenishes fluids and then fat.
Recent families I have supported with at breast optimisation (no pumping etc. needed)
👶 oral dysfunction and reflux 56g a day
👶 > 10% weight loss in early days 250g in 3 days
⚖ I don’t want families to be dreading weight checks. If we have the right plan in place, know what to look for in baby's feeding, then appropriate gains are to be expected. If these are not happening then this is more information for next steps.
✨Feeding support people: Consider reframing “this baby is just gaining slowly” to "this baby is consistently gaining weight below expected for age”. If you are not sure why or what plan is needed refer on. For more information see www.breastfeedingsupport/supplementingtheunderweightbaby https://cks.nice.org.uk/topics/faltering-growth/
