Hmmmmmm.... When I read your title my first thought was that there was a night feed interfering with the morning feed, but given that she's STTN from DF until 7 that obviously isn't the case. You could try bringing the DF earlier but I can't imagine it making much of an impact, especially at this young age. Breastmilk is so easily digested that her stomach is definitely empty in the morning!
A few thoughts...
- Could you have a really strong letdown? After 11.5h your breasts are likely quite full, maybe she's having trouble handling the flow?
- Do you feed right away - in the dark bedroom, maybe even before she's fully awake? Maybe she's distracted by the world around her (this is the prime age for a distractible feeder) and just would rather look around. The bottle would be ok because she can have a look around the room while she's being fed.
- Or complete opposite, maybe she needs a little bit of time to wake up? Get her up, change her diaper and dress her, let her *realize* that she's hungry?
- Could she be taking a good feed in that short time? As babies get older they get to be expert nursers and can take a full feed in a surprisingly short time.
What do you think?
