Hello my 6mo baby has got into a routine where she won't sleep unless she has full on meltdown first. I've tried getting her to sleep early when she first shows signs if tiredness but this makes it worse. She only started doing this month or so ago and I don't know how to break habit. Is this normal? She has pretty severe silent reflux so from v young got used to falling asleep being held because of having to be kept upright & I can't change that at moment cuz she still suffers but wondered if the meltdown was normal for her age?
