My baby suffered with bad wind and colicy reflux until she was about 4 months. For a couple fo months, it was much better, not bringing up much of her milk and bringing up some good burps. The last week she has been really windy again and is bringing up so much milk I'm having to change her and my clothes several times a day. Now she won't nap during the day because she can't settle. Fortunately she has reverted to screaming because she's tired and fingers crossed I'll get her to sleep before then.
Any ideas why she is suddenly windy again. BTW. I can't see any obvious teeth.
