Takes her about 15-20 minutes, and she eats 4ozs at a time. She is still using a slow-flow nipple. I've tried using a fast flow (stupid VentAire bottles don't have a medium flow) and she chokes and it goes everywhere! Probably going to use slow flow for quite a while at this rate..
Re: FF:How long does it take ....
It takes DS about 15-20 min to finish a bottle. He is at 6-8 oz per feeding. We are on the medium flow, and also use drop ins.
