Or maybe you just call them "meltdowns" instead by this age?
My ds has had lots of tantrums, since he was about 2.5yo. I think it probably peaked around age 4-5 but he still really loses it about once or twice a week. He can go from 0-60 in an instant, and totally loses control of himself. Often it's over something minor, like today when I opened the biscuits and he wanted to.
When he starts screaming/banging chairs around or whatever, I try to just ignore him until it passes. It can take at least 30 mins sometimes. Sometimes I put him in his room but I would have to physically "escort" him. If he's getting very destructive I have to intervene obviously. He screams that he hates me, I'm so mean etc etc. When he's calm he is fine, very affectionate, a normal energetic boy. He is fine at school, the meltdowns only happen for me and DH.
I thought he would have more control by now - anyone else have experience of this?
