Dd aged 4 has suddenly decided she can't sleep without me beside her. She's usually ok, we have stories then a lullaby and then I leave usually by around 8pm and she settles herself if the lullaby hasn't already knocked her out. But lately there's been massive problems and tantrums at bedtime, the usual need a wee, need a drink, then she says she's had a nightmare (even though she hasn't been asleep to have one) etc etc and it all escalates into an almighty shit storm. I'm usually ok at handling tantrums and leave her to it to rage herself out, and then go in for a cuddle when she's calm, but the bedtime ones are a new thing and they just go on and on until I give in and go and sit with her. Not sure whether to be firm and make her go asleep on her own for a few nights even if it means her 'crying it out', anyone any wisdom?
