ADVICE!!!! So my son is 7 days old, he got discharged on Wednesday night. I’m not sure if this is postpartum depression but for some reason I can’t sleep when my baby sleeps because I keep having nightmares that something bad happens. When he sleeps I have to stay up and watch him, I check every couple seconds. He makes a noise and I get really scared. When I’m in the car I think I’m going to get in accident and sometimes I think someone is going to steal my baby. When I was in the hospital, in my head I thought he had a seizure while he was in the intensive care unit (I have epilepsy, and so does his grandmother;father side), it scares me because I think he going to get sick. I literally went through about 10 outfits on him today because I think it going to hurt him if he’s dirty and I want him extra clean all the time. I had a lost prior to this baby (he was born at 23 weeks) and This baby was born at 35 weeks and 5 days. I’m not upset or anything I actually enjoy these moments with him and I’m like overly excited. I don’t feel depressed it’s just I feel like something is a little off about me. It’s like I have OCD or something.

I know you guys aren’t doctors/therapist/psychologist but I just want to know if anyone ever been through anything similar.
