I'm running out of ideas here so I hope someone can help.
About three weeks ago DS started refusing his bottles. I thought it was due to his cold and teething so I just let him take what he wanted and top him up with water and cereal besides his solids. Now though, he has not had a bottle for the last 24 hours - not a drop. He refused his afternoon bottle yesterday, then his nighttime bottle. I even tried to dreamfeed him and even asleep he refused. He woke up 2am (though this is not unusual he's a bad sleeper) I thought he might be hungry as he hadn't had his bed time feed, again he refused. He refused his morning bottle even though he seemed really hungry. He had the entire 7oz mixed with cereal and would have taken more if I had let him.
I'm not sure what to do now. I'm using Avent bottles and just bought size 4 to see if it helps, bit it has made no difference. The same thing happened with breastfeeding about 4.5 months, he just started to completely refuse, which is how we started bottle feeding.
