DD is 15 weeks and I'm getting to the point where I'd like her to start going to sleep on her own. I'm thinking of getting her used to a comforter but I'm not sure what would be best to use. Something easily replaceable seems a good idea, and I've heard people recommend a muslin square, but I'm worried she'd try to stuff it all in her mouth, or wind it round her neck. Am I being over-anxious? Or is it too early for her to have something in bed with her for naps and nighttime? I'd be interested what other people use and when you started to introduce it. Thanks!
