My daughter is almost 6 months old & has developed a really annoying habit. Ever since she learned to roll she rolls from her back to front to sleep, fine. But then she will wake out of her sleep to lift her head and look around then put it down again and repeat!! She’ll do it I kid you not, a good 20 times back to back, to the point that she completely wakes herself (and me!) up. Is this normal? Please tells me it goes away soon, i’m at my wits end
