My boy is 7 and half months old, I need to return to work and would like him to start taking milk in a bottle I intend to give him expressed breast milk and maybe transition to formula. Every time I give him a bottle he moves it to the side and just chews the teat. He originally had a tongue tie and used the MAM bottles however, we haven't used a bottle since he was 4 months. Iv tried the MAM, Tommie Tippe, own brands etc. Yesterday I purchased nanobébé but he still seems to do the same thing. What do I do ? I also need him to take the bottle as iv tried everything to get him of nursing to sleep but can't and he wakes about 5 -6 times at night. So I'm hoping this will kill two birds with one stone but I don't know what to do to get him to take the bottle. Any help or guidance would be much appreciated. Thanks in advance.
