The baby keeps waking himself up with his hands and won't let himself fall asleep. He keeps rubbing his eyes constantly. We wrap him in a blanket but he quickly gets out of it. And he is six months old, I think it's time to do without blankets, especially because of the heating, it's hot and without a blanket. How did you solve this "problem"?
