Anyone got any ideas on how to deal with a baby (18 weeks) who has just started screaming before a feed? He's obviously hungry and yet screams, turns purple and refuses to take the bottle. After about 5 minutes he takes it and away we go. Occasionally he will then scream mid-feed and we will start all over again. Other times it's all as normal. Up until now, he's fed fine with no problems at all. I've been careful to wind him so don't think it's that. All thoughts welcome!
