My DS is 9 weeks and EBF. He has taken bottles of expressed milk since he was about 3 weeks. In fact at one point I think he even preferred it. All of a sudden he is refusing to take a bottle! I haven't changed bottles or done anything differently. I'm in a panic as my DH does the 5am feed with a bottle while i sleep through and I don't want this to end! Has anyone had a similar experience?
