I don't think a split feed would work...this was her morning eating wise:
5:45am 5.5oz
Took her a bit to settle here, and she had a rotten ot day yesterday because of short naps so I let her sleep in
10am 4.5oz
11:20am 5oz
Nap 12-12:45
1:45pm 5oz (this was the difficult one because of the long A +45 min nap)
Nap 2- ? It's 4pm and she's still asleep, just going to let her sleep I think

It's almost like she needs 14 + oz in the am in addition to any nfs before she can get a good nap. If I don't do two feeds in that am A then I get short naps all day because she's always behind if that makes sense?
