When my 14 month old DD gets frustrated/angry she will hit me, or objects or herself.

If i leave the lap-top open, she will have a look and maybe push buttons. If i come near her, (when she realises that i am there) she will start bashing at it. I then take it away because i don't want it broken.

When she hits herself, she will bang at her head with her open hand.

She has not been hit, and hasn't seen other people being hit, but i'm not sure how to handle it.

If she is hitting me, i either put her down on the floor (if it is safe) or put my arm up and say 'no hitting' and try to calm her down.

Sometimes she will then hit herself, and then i hold her hand, 'no hitting bub, it will hurt'.

It's hard to explain in words, i am not restraining her (cos that would make her more frustrated) but am trying to stop the hitting, and calm her down.

Any ideas?
