When she was newborn my daughter escaped swaddles so we put her in sleeping bags, then as she got old she unzipped herself from sleeping bags so we put them back to front.
Around 13 months she managed, god knows how, to escape. So we moved to one with shoulder poppers only. She got out of that.
So at 16 months we tried a duvet, she hated it, kicked it off and would wake if we put it on her after she was asleep. So we tried a togged sleepsuit with popper on the front. She has now at 18 months learnt to escape that! I can't put this back to front because theres not enough fabric for her bum.
Tried the duvet again for a few nights and she's not having any of it and just getting so cold!
Any ideas would be greatly appreciated! She's definitely not too hot, our house isn't particularly warm. We've been trying to introduce the duvet and having blankets on us for months now. She love being 'cosy' under them downstairs but hates them in her cot.
