Newborns suck their thumbs as part of the suckle (sucking) reflex. If a baby cannot suck, it cannot get nourishment and without medical intervention, the baby would die. As a newborn ages, a baby sucks because hand-mouth exploration is one of the primary ways babies explore their world and learn. Babies may even try to suck their toes! As babies learn to scoot, then crawl, then stand and walk, they ignore their toes for sucking but still return to their thumb when hungry, tired, frustrated, or need self-comforting. Now, they don't need the suckle-reflex but sucking the thumb lingers because it is comforting. By 2-3 years old, toddlers typically stop sucking their thumbs, but many still do until pre-pre-school at age 4. Still many 4-year olds return to the thumb when very stressed. Children who persist in thumb-sucking may need adults to help them to stop. However, many kids still periodically suck a thumb once in a while even up to age 8-9 years old. But by then, kids realize their friends will make fun of them. Between social milestones and peer pressure along with parental guidance, most kids stop thumb-sucking without problem before age 4. If you are in grade school and still suck your thumb sometimes, try putting a band-aid around the thumb as a reminder to stop. Kids who suck thumbs beyond age 4 can mess up the alignment of their teeth, pushing the top teeth forward like Bugs Bunny. This often requires braces later to correct tooth alignment. So whatever you can do now to stop will help you in the long run.
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.
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.
