At the hospital they kept letting us know it was important to keep cap on baby to help her regulate her temperature and keep her warm. Of course now we're home and the grandmas are all about the cap too. But K lost a little over 10% of her birth weight and even the smallest hospital caps keep sliding down over her eyes! I don't want to let her sleep in her caps anymore. Did you let your NB sleep in their caps? I need ammo against the grandmas now. Getting so nervous but K has is all pulled back so like 1/3 of her head is exposed.
