My 3 month old started daycare this week and I started bringing 3 4oz bottles of breast milk. They said she eats them super fast and is still acting hungry, so I started bringing 5oz bottles and they said that didn't seem to make her much happier. I can't imagine that she needs 6 oz bottles, but I also don't want her to be miserable. Are there bottles that will force her to eat slower? I just think she is eating to quickly and doesn't realize she is full.... Any advice would be appreciated!
