Girls, can you please tell me what's wrong with my baby who is 1 and 2 months old? Today is the second night he starts crying and won't wake up, he can't be calmed down, only when I pick him up does he start waking up and calming down. We can't get him back to sleep for 2-3 hours, we just sit and watch cartoons and he falls asleep like that. My friend's two-year-old has the same thing, they have been having this for two days, it seems like something is affecting them, anyone had a similar case? Should I go see a doctor?
