I was faced with the problem that my four month old daughter stopped sleeping normally. She often wakes up at night, does not give rest, I have to get up to the child 7-10 times a night. Until four months, my daughter slept perfectly. But as soon as she was four months old, the child seemed to be replaced, nothing helps. Is this https://www.nestedbean.com/blogs/zen...eep-regression the 4 month sleep regression? Who else has this problem?
