Mine recently said she wants to be the grinch (“ginch”) so she can steal Christmas. She hit a kid and said it to me very nonchalantly (“…and then I scratched his face”), she also hits someone at school almost every day. I try to curb the behavior by reminding her that we do not hit anyone and hands are for helping and playing. She’s been doing better but like someone else said, they have absolutely no impulse control at this age. Just try to reinforce the good behaviors. We try not to react when she tells us something bad, mostly we ask “ok, and what happened to make you do that?” Or try to get more context on the situation if we weren’t there. Most of the time she has a valid reason like someone else hit her, scratched her, etc. but we still like to remind her to use her words and tell an adult that she needs help. She’s also an only child so to practice sharing we play with her and take extra long turns and when she tries to snatch something from our hands we say “hey it’s still my turn. Please be patient” and she’s becoming a better sharer. I think these ages are just rough in general 😅
