Didn’t read some of the other posts so sorry if I repeat anything. My plan was to keep dd in gro-bag for as long as possible but she started pulling it off and jumping all over the cot so switched to a duvet. An idea I heard was to put the gro-bag on backwards. As long as the neck isn’t too high I think this would be great but I had already switched over.
To switch..it was summer here so I got a light duvet/coverlet but put PJ's/nightdresses on DD in case it fell off.
I named her coverlets...one had bunnies on it so I'd say lets cuddle up and go to sleep with the bunny family…. and we 'd pretend to be quite to let the bunnies sleep. I also made a big deal about tucking her in snugly which she still loves.
Fro the first two nights it took her longer to settle but then she was fine, I check her every eve once she is asleep and at first I had to replace the duvet every night but she is getting much better and I didn’t really worry as she had pJ's on.
This week she changed to a bed again sooner than I planned too but on holidays in one of our relations she had to sleep on an air matress and she stayed there all night so I decided to make the switch at home..so far so good..but I think getting her used to the blanket in the cot really helped.
Anyway HTH
