Hello everyone) Girls, how did you cope with the first month of sleep? The baby doesn't sleep at night, sleeps during the day but not for long. It cries endlessly, has tummy pain. Is this your first month like this? I myself am not getting enough sleep, even when she sleeps I want to lie down but as soon as I lay down she starts crying. During the day I don't sleep... there are still 40 days left to be home... in general, it's hard to go crazy)) depression maybe? Has anyone had this? How did you cope? Hormones are playing right now...
