I have dd in one since she was about 6 months. They do limit in a certain way, as in they can still sit up, remember doing a whole nap time of putting her back down
, they can roll around as much as they want and I used to find dd at either end of the bed at any time. DD can now stand up in hers but she has been walking for almost 10 months and it's only in the last few she can stand up in it or at least decided to. The best part of it though is that she can stand but she can't lift that leg up to try and climb out
so I will keep her in it as long as possible. She is in a 6-36 months one so has hopefully another year in it if she doesn't move to a big bed. Oh yes, she too would like to unzip it but it zips from top to bottom so bit difficult for her. Branwen when I take it off she says hi to her feet
and we have to kiss them before they go into the bag
