Tan - DS does this, he usually gets himself so frustrated that he slams his head on the floor. I think its just him working through his emotions, and after he does it he seems to get over it.

IMO (and its only my opinion) I think its good to let them express themselves, because its something we can't really help them do, yes we can help them discover measures to control their temper and frustrations, but I'm not sure it really works for that age group yet.

We just let him go and get it out. He's hardly going to knock himself out, and its a lot gentler than hitting him every time he chucks a tantie. He goes to hit us sometimes, and we just take him by the wrist, and tell him that we don't hit in this house, and that's not being nice to mummy/daddy (and put on a real disappointed look) and it seems to work so far...

I dont' really know if its considered gentle parenting (mainly cos I haven't read any books about the subject) but its not hitting them at least.. lol
