My 4 week old DD has recently been very fussy with her bottle, crying and then refusing altogether less than half way through. I read that this could be a sign that she was finding the flow too slow (even though she is still very little) and getting frustrated. I tried level 2 Dr Browns teats today for the first time and she took a whole feed with no fussing at all and no crying! She did, however, finish the 4oz within 15 mins and then projectile vomit about 5 mins afterwards
Was this too soon to move up a teat or will she get used to it? Have others found their baby was sick if they move up a teat size?
