DS was 8lb5oz at birth. He lost quite a lot of weight in the first week due to severe jaundice, but then caught it back up again, although he never quite got back onto the same percentile.
I've just weighed him again (first time in a few weeks) and he's apparently dropped from around the 78th %ile to the 48th (this is using WHO values for breastfed babies).
He's EBF (every 2.5/3hrs). He has lots of wet/dirty nappies, seems energetic, and is definitely growing out of clothes. He does have reflux and brings up at least part of every feed, but it doesn't seem to bother him.
Is this a concern? What do I do?
