DS, 5 MO is showing signs of becoming a comfort blanket kind of a chap. He's particularly fond of a crocheted blanket with holes he can stick his fingers through (we don't give him this at night btw, only when he's being supervised). He likes to grab hold of a piece of fabric (my t shirt if necessary) and rub it against his cheek to help him get off to sleep. It's really cute to watch The question is, is it a good thing he's got something that makes him feel relaxed and sleepy, or will it become a headache when he's older/the blanket has to go in the wash/the blanket gets lost/we want to go somewhere and we don't want to trail a grubby and holey blanket with us?
