neocate is thinner and moves faster through her body (not as fast as breastmilk but faster than typical formula), so I would maybe up it an ounce and se how Ava does. If she spits up a lot of it, or her reflux acts up because her tummy is too full, you will know and then you can back off a bit. She is going to be three months in a couple of weeks, so she may be able to handle a bit more.
sounds like she is eating like a champ! If she eats more during the day and sleeps better at night, then HOORAY!!
