My baby is 7 months now n still wont sleep thru the night she wakes for bottle even though i give her a jar n bottle before bed shes stubborn?

"Trained Night: Feeding" occurs ~ 6 mos. & persists till you ignore her night-crying consistently, even though it gets worse for a few nights before it stops completely. Establish a consistent bedtime & routine; read, brush her teeth after her last bottle & put her in her own bed, drowsy but awake, so she learns to self-calm to fall back to sleep. See www.Aap.Org for tips if you're tempted to go in her room.

That is normal: Some babies sleep thru the night, and some don't. Yours seems to get hungry at night. But there may be other causes for waking up. Diaper wet, any rash on the butt? Any noise? Etc. Your baby may wake up at night for one of these reasons, not for hunger, but he may find comfort in sucking and fall asleep. You may need to look at the whole routine. But some baby does need more food than the others.
