my DS of 18 months hasn't been in a Grobag since Christmas as he grew out of his last one and I didn't have the cash for a new one, so used sheets and blankets instead - I've put him in a new summerweight one this evening and he didn't seem to mind, but will he still be able to turn over etc? It's been a long time!
I stopped using dd's one when it got warmer and she was about 17 months. She was getting very frustrated because she was getting a bit corkscrewed and couldn't move very easily. Am going to try her again with it. She was still able to turn over, she just couldn't climb all over me
