Should we be seeing a pead doc. Plunket seamed to just want to do what I wanted to do. I wanted more direction. He isn't pacific island - a lot of people ask that
He is higher than the 97th percentile currently for his weight but what about his head circumference and his length. Are these consistent with the same growth pattern? Most medical guidance on excessive weight gain at this age for breastfed babies is not to worry. There are some (very) rare conditions where babies are very large and gain weight very quickly though there are usually other concerns which are apparent.
Were you or his dad very large as babies? Did you have gestational diabetes?
Without knowing more information I cannot advice you further. But honestly, if you’re worried and it sounds like you are, then you could request a referral to see a paediatrician, either through your GP privately or at your local children’s hospital. Think about his feeding pattern, if you feel he’s feeding excessively then perhaps you’d want to think about cutting back on his feeds. At four months of age, around 5-6 breastfeeds in a 24 hour period is reasonable if the mother has a good supply and the baby is feeding effectively. Avoid starting solids too early, this is likely to add to his weight and size. Six months is the current recommendation.
