I have an upcoming overnight trip and need my baby to take a bottle. She is just over 8 weeks and I have tried everything!

I’ve tried different bottles, but the only one she seems to somewhat tolerate is the mam flat nipple. I’ve read to try different feeding positions, such as feeding them on your lap while they lay on their side. No luck!

Her dr claims she doesn’t have a tongue or lip tie. But she gags so much when I try to feed her a bottle. Do i need a shorter nipple? Are there bottles with short nipples?

Anyone else have this issue? If so what did you do?
