I'm worried about DD. She has been a very hungry baby from birth and is now more than twice her birth weight (just under 4lb - she was born at 34 weeks). She was always eating a bit more than the recommended amount up to this week or was waking up hungry every 2 hours (on a premature milk formula). This week I can't get her to keep more than 4 or 5 feeds a day down - even though I started giving her the recommended amount in case it was too much for her (in that case why did she take it before?) It's a bit of a mystery - has anyone had this? It's more than a posset, a proper projectile vomit.
