DD is about 3 1/2 months old. The last week she has been VERY fussy - DH was up for one night solid with her crying, nothing would console her. The rest of the time she's still really fussy. Up until now she has been a very laid back, well behaved ;) girl! She has a little bit of a stuffy nose, and with her pacifier or if dh tries to give her a bottle she really works her mouth over them instead of just sucking. After her NICU stay she didnt' have much interest in nursing when she came home, but about 3 weeks ago she latched and seemed to prefer that over a bottle when I wasn't at work. I nursed her as much as I could. All of a sudden she doesn't want to nurse anymore and she's not eating as much from a bottle either. When the fussiness first started she was spitting up a lot more also, so I've cut diary from my diet for the past week. We have also had a few diapers that aren't normal for her. They are very rarely seedy, they look more like yellow paint, but a few have been green and more runny/watery.
Could it be teething? Does she just have a cold and the congestion has her tummy upset and is affecting her appetite? Colic?
Any input, advice, etc? My poor DH is about to pull his hair out during the days - he's laid off right now so he is taking care of her while I'm at work.
