Question... so my little one is 6 weeks tomorrow and slept thought the night for about 5 weeks but the last 3 nights she's been non stop screaming from around 9pm - 2pm I've tried everything skin 2 skin, changes, feeds, burping, rocking but nothing seems to work. Does anyone have any idea why?! Or is it just her getting more active? She sleeps fine in the day in her Moses basket but the second it's bed time she has none of it
