My LO is 12 weeks old and EBF. However, I'd like him to take a bottle so that way my SO and I can go out for a few hours and have someone watch him. I introduced a bottle to him around 4 weeks and he was fine with it and this past month he is REFUSING the bottle. On the very few occasions we can get him to take a bottle it takes him close to 2 hours to drink it, with fighting and playing with it the whole time. We've tried different bottles and nothing seems to help. Does anyone have any advice??
