My Daughter, the Crab-turtle

Do they make muzzles for children?

If so, I need one. And some type of straight jacket thing where the child's hands are restrained would be helpful too.

You see, my daughter, Ladybug, thinks she is a snapping turtle/crab hybrid. Instead of a rosy, smiling mouth, she sports razor sharp teeth which she wields with great accuracy. Instead of hands, she has pinchers and she is not afraid to use them.
Every time Ladybug gets mad or frustrated or is told no, she lashes out either by pinching or, now, biting.

The pinching has been going on for several months. She gets upset about something and whips those little fingers out and gives whoever is closest a good pinch. If no one is close to her, she will pinch a toy or the wall (which is pretty darned funny).

Yesterday, she added biting to her repertoire. Three different times during the day, she got mad at her brother and bit him. Bit him hard too.

Obviously this has to stop. We have been using time outs and diversion, but are getting nowhere fast. I know this is normal behavior to a certain extent and I know it stems from frustration and will likely resolve itself when she is more vocal, but I am not comfortable ignoring it. I am especially eager to nip the biting in the bud since she will be in daycare in August and I don't want her to get kicked out for biting.

Ladybug is very high-strung and always has been. She was angry from the get-go and has always had a temper. We used to think she would grow out of it, but I am beginning to think it is just her personality. She will have to learn to control herself at some point.


Nothign we have done has worked. Timeouts and stern no's have had no effect. Diversions don't work. Short of a muzzle/straight-jacket combo, I am at a loss. Any suggestions?
