Have something they do to help them sleep? From day one Sebastian has loved hair! At bedtimes when he has his dummy his hand immediately goes to his hair and he strokes and tugs it and at nap time when I cuddle him he seeks my hair. If its tied back I usually untie it and as soon as he has a handful of hair he's away! He's currently fast asleep with a massive handful of my hair! So do your LO's have anything similar?
