Hello everyone! Could you please tell me why the baby cries while falling asleep, already for a week now, I feed him, hold him, rock him - still crying. And only then does he fall asleep with difficulty. Although during crying, it's visible that he is sleepy, with half-open eyes. Teeth are sticking out or something? We don't have colic, the tummy doesn't bother him. Is this normal at such an age?
