My 2 year old boyyy

He’s started hitting! Lol. He’ll smack his 4 year old brother in the face if he gets him mad. He’ll hit me, tries to hit my face if he’s close enough.

I’m not sure where he’s picked this up! My 4 year old doesn’t hit him. He does visit his grandparents on his dads side whom also has grandkids over at the same time.

How do I get him to stop? I told him “don’t hit” & he’ll just get mad and say “no” and hit again. I tried to ignore him, continues to hit. I hold his hand, gets mad lol. I’ve seen him try and hit a girl at daycare because she was tryna give him a toy 🤦🏽‍♀️
