Has anyone else experienced their baby not really wanting to eat from their bottle or boob. Mine is 6 months But isn't really eating baby food yet besides cereal. It takes her a pretty long time to finish a bottle because she'll drink some but than push it away even though it's her feeding time. she's been really wanting to eat solid food like 10 minutes ago I had a snack, but she threw the biggest fit because I didn't let her have any. I also believe since she's been teething for a while now that could be a small part. I just want to have some advice since her doctor appointment isn't for three weeks since that's the only time they could get me in.
