I've read a few threads on here either saying that people shouldn't use props to get their babies to sleep or that they want to get rid of them. I was wondering why and what constitutes a prop? DD is 21wks, has always breastfed to sleep but whilst we were on holiday last week I noticed she fell asleep twice using a muslin either to suck on or just hold. My DM commented that this would become a blankie if I wasn't careful and DH seemed a bit concerned too. I, OTOH, was pleased that she'd naturally found another way to get herself to sleep, particularly as it's now scorching hot and she really doesn't want to be cuddled up to me feeding, getting all hot and sweaty. I just was trying to feed her to sleep as she was tired but she didn't like it so popped her in her cot and gave her a muslin and she's gone off in less than 5 minutes. Is this really so bad? I actually thought it'd be better for her to cuddle a muslin than 1 particular toy because I have loads DD of muslins whereas a toy can be lost and possibly be hard to replace. So am I making some huge parenting error?
