Approximately 3-5% of U.S. males, age 15, suck their thumbs. It's a "normal" habit but often hidden due to the social stigma attached to it.
Thumb sucking at age 11 is indulged in by about 10% of those that age with the ratio of female to male being about 2:1. As such it's "normal" and, in fact, can be found in about 2% of the adult population of the United States.

No. But don't suck on your thumb, it's weird.
They CAN suck their thumb, however by that age, they should have grown out of it.
No.
Babies mostly do
Buy some aloe vera and put on it when child is unaware. Then when he/she is going to suck their thumb they will have a bitter taste and wouldn't want to suck it again. Or try other alternatives you can use to put on your child's thumb. Also you can try putting a bandage on it to prevent them form sucking it.
Sucking of the thumb is a bad habit that cant be stopped easily. Wrap paper tape on your thumb if it there you wontwon't want to suck it. Do this for some months. The habit should stop.
