My DS is 5.5m & I think he's going to be a comfort blankie boy as he loves to fall asleep with a cellular blanket or muslin next to his mouth/nose. He also can pull them over his face...hmm.
At the mo I check on him everytime he goes quiet when he's falling asleep just in case!
Surely there's comes a point when I don't need to do this? I just don't have a clue when!
