Girls, hi! Can you please tell me when the daughter gets angry or starts biting and scratching herself even in her sleep? What could be the reason for this? To which specialist can I turn? It's just that she goes straight into strong tantrums, it worries me. We refused from pacifiers two weeks ago but there were no problems before that. We also had her scratch and hit herself before, but literally 3-4 days ago, she screams at night and the husband bought pacifiers again and she started sleeping more calmly, but still, she is somehow restless and might scratch and hit herself. I already thought of putting scratches on her hands ? but she will take them off, so we need to solve the problem
