so,Hunter is on a very good schedule..hes goes to sleep at 9 and takes a nap around 12 or 1 for 1 to 2 hours. for the past 5 nights he's whinning in his sleep maybe some whimpering but not crying and he doesn't wake up or he doesn't seem like he is. Is he too young for nightmares? or has anyone else been through This? he's only a little over a year.
