My 3 month old ds is breast fed but used to take an expressed bottle at night. He started refusing it though, and my dh had to wake me to feed him, so I stopped expressing. Now I can't leave him for more than a short period because he won't take a bottle. We've tried Nuk medium flow and Avent 2 hole but he hates both and screams when he's offered them, even when he's starving. Does anyone have advice on how to re-introduce a bottle?
