Hi, I just wondered if anyone else's baby got really fussy at three months? My little boy is 12 weeks on Sunday and usually very content but this week has been very unsettled at night, spitting dummy out, waving his arms everywhere and waking himself up then crying. During the day as well he is not himself, and gets upset very easily. He's also needing feeding more so I thought naybe a growth spurt but he hasn't put on lots of weight in the last fortnight so wasn't sure, is T too early for teething or the sleep regression?
