Does anyone else's toddler hit them

Dd is 3.5 ans she has never been much of a hitter.

yep. I was proactive and beat him to it though. All 3 of mine (all boys) went through a short stage of this at different ages. I stopped them as they brought their hands up to smack. I'd grab their little hand/arm right out of the air and STERNLY tell them NO HIT. After a little while it stopped them. Sometimes other consequences went along with it. like time out, or a spank (yea yea hitting for hitting whatever, it works for some kids not for others and everyone is different) Sometimes telling them you won't talk to them until they stop is enough. one of my kids is very emotional and that worked for him. I ignored him if he tried to hit. Nothing he did even when he was bad I wouldn't rise to it.

Headbutting is my sons favorite! Talk about taking someone out at knees, literally!!

No really. When he's really frustrated he sometimes slams his hands on the bed.

Yes, espeically the last two weeks (it has been really bad) She is around her teenage cousins during the day and they physically fight with each other and she sees that behavior and does it at home. On the weekends when it is just us, she doesn't do anything of the sort. 2 years 2 months

Yes, but HARDLY ever

My youngest has done that before. When he was frustrated. I would tell him that hitting isn't nice and we don't do it then put him in time out.

my son hasn't done it really. he's tried a couple times but quickly stopped.

Mine is 2.5 and he does this also. I just put him in timeout.

don't let him.. if thy start thy will hit other and get in trouble.
