Hello! Girls, help me, I'm about to go crazy. My baby is one month old, we don't sleep at all through the night. He sucks on my breast, falls asleep in my arms, I put him in his crib and he wakes up and doesn't sleep for minutes, then starts crying quietly and so every night already for 4 days, eats well, has no constipation or colic. The baby was born without pathologies, he used to sleep well, but now for 4 days it's been like this. And during the day he sleeps.
