When my daughter went through a phase of throwing things, I’d hold her hands and calmly explain why she can’t do that. I’d reinforce “nice hands” or “nice words” when she was having a tantrum. I’d also put her in timeout. I’d have to sit with her to make sure she stayed there and I’d talk to her about why she was in timeout. After, we would hug and apologize.

I noticed my daughter does it because she can’t talk that well and she gets frustrated when I don’t understand what she’s saying or wants

When my son was doing that it's because he was getting upset because he couldn't talk that well and he was taken him anger out. But come to find out he had sensory processing disorder and speech delay.
