Hello everyone ? The child almost doesn't sleep all night periodically, refusing daytime naps. Today he didn't sleep at all from 2:23 am to 5:40 am, he slept twice during the day, but the first one lasted 30-40 minutes, and the second one 15 minutes. We went to see a pediatrician, she said that it happens up to a year old ?‍♀️ It's already impossible, my brain refuses to work because I don't sleep. Has anyone had this happen? What did you do?
