Girls, hi everyone! We've been having trouble sleeping for several days, both day and night. We're getting used to the clock's rhythm, but it keeps waking up, worrying about it. At night, he doesn't want to sleep in his crib, I turn him over every 10 minutes, he wakes up. Now he sleeps with us. During the day, if he sleeps an hour, he wakes up three times during that time. He pulls all toys into his mouth, if he can't, he gets nervous because of it. There's no drool, could it be that the teeth start bothering him? What did you use when your teeth were cutting?
