Hello. Almost 38 weeks. I feel like I want to sleep all the time. Especially in the evening, around 8-9. Is this normal? This hasn't happened during my first pregnancy. Now, I close my eyes as soon as I hear the door closing and turn on a cartoon for my son. Then I fall asleep for half an hour. And then I think: am I a good mom? ??‍♀️
