I was warned by my daughters pediatrician that around 6-8 weeks baby would become more fussy. Well 6 weeks is here and she gets really upset for about 15-20 minutes in the evening. All day long she is fine, not fussy at all. During those 15-20 minutes she cries very hard and is pretty much inconsolable. Once that time passes, she'll usually fall asleep or calm down and then she's fine again. I've noticed it's right before the time she gets ready to sleep for the night (she sleeps very well through the night, only waking to eat). Has anyone else experienced something similar?
