The bottle MAY get you home faster but there is no garauntee with this. To me, they sound like they are acting exactly like their gestational age. The suck reflex starts to come in between 32 - 36 weeks gestation, and the ability to co-ordinate sucking, swallowing and breathing comes towards the end of it. Some babies learn it quickly, some not so fast. Is there anyone in the nursery that can sit and watch you feed? Sometimes prems just need a slightly different way of attaching.
