Typically how long does it take your LO to drink a bottle? My little guy takes about 40 minutes to go through 4 1/2 oz. I know every babe is different, just a curiosity question.
Also anyone know what cues to look for to bump up to the next level of nipples on the bottles?

Re: FF ?
Mine takes anywhere from maybe 30-40 minutes. It really depends on her & what bottle & nipple we're using.
Wondering about the level of nipples too!
When my LO takes a bottle of pumped milk it takes about 15mins or so including burping but my little guy chugs his bottles!
When he seems frustrated with the flow then you may want to try the next level of nipple.
