help!!!

What can I do my 3 month old daughter just got a habit of only wanting to eat when she’s falling asleep she will not eat if she’s wide awake I always have to wrap her up then put her pacifier when I see she’s closing her eyes I change it up to her bottle and that’s the only way she would finish it.

If i try to give her the bottle when she’s awake she would just want to throw up I know she’s hungry too she just will not take it if not falling asleep

Im just scared I’m not giving her enough formula she’s only taking 20 oz a day
