In the past few days my dd now 22 months has realised she can zip down her sleeper suit and get out of it - all apart from the one button at the neck but she still manages to get legs out of it... This was OK as she used to take it off in the morning when she woke up and I was just thankful she left the nappy on... problem now is that she removes it when she goes to bed and kicks up a stink in the first place for us to put it on. The last few nights I have been putting her back into it once she's asleep.. but last night she cried and cried until I took it off her and put on 'big girl pjs' - really summer time ones she had received as a present. I am more concerned she will be cold overnight as the sleeper suits were nice and warm (fleecy ones). And also I have bought a number of them for the winter. Is this a phase that will pass - should I insist on putting on the sleeper suit at bedtime and then just put her back into it once asleep - or go out searching for warmer 'big girl' PJs ? She moves around a lot in her sleep and we've also tried the grobag sleeping bag with no success - (probably should have started when she was younger). Any advice ? Thanks a lot.
