My daughter has always been an easy going baby since she was born, hardly fussy and easy to please. The last week she has been very fussy and irritated by everything, even when we are playing she wants to whine and nothing I do pleases her. She is currently getting her third tooth, so I know it could be just her teething but I was wondering if any other mamas went through the same "fussy period" with their babies. Did it eventually get better? Also, she goes to daycare...possible she is picking up from other babies?
