DD1 never had one, well except for my boobies and had to put a stop to that as I couldn't always be there! Anyways, DD2 has become very attatched to her blanket, she always has loved it but since she was unwell last week I've seen how much she loves it, as soon as you give it to her she gets so excited and rolls over, is all sleepy and settled.
If she is cranky in the evenings get it out for her and she sits there happily.
My mum knitted it so I've told her to make a couple more for me to keep in the car and nappy bag lol cause I'll be worried if I lose it or if we forget to take it somewhere.

So what is your child attached to?
