Hello everyone. Help, please, tell me, I need your help. The situation is that a little girl, 1.3 years old. It seems like a week or more, I can't say for sure, it started throwing tantrums, in any case, especially when I don't give her what she wants or when something doesn't go as planned. It manifests itself with tantrums, demonstratively lying down, and even hitting the floor, screaming and yelling at you, and you can't calm her down.
