Booster Seat

I love my new booster seat. It attaches to the back of a chair, and a seat belt keeps me in it. The only thing it lacks is some way to make the chair itself secure. This morning I pushed with my feet against the kitchen table, and my whole chair fell backwards and hit the floor, with me in it. I am not sure what my head it, but it was probably the chair back; anyway it hurt a lot, and I cried for about 10 minutes. I feel better now. Time for a nap, but 'ouch'.
