Thumb Sucking

Infants have a inborn sucking reflex related to survival, obtained usually via breast milk. The association with pleasure often leads into a habit and, since hand-to-mouth is a common reflex also, the thumb enters more easily than the other fingers which are also sucked by a less populated number. This habit can continue through adulthood, and often does.

Babies practice swallowing and sucking in the womb in preparation for entering the world so they can breastfeed. Sometimes it can cause them to get the hiccups inside your belly as well! :)

As far as I know there is no historical reference that attributes the trait to King John. It appears to be a total fabrication.

Posh Spice (singer), Madonna (there are many photos of her sucking her thumb), Rachel Williams (British Model and actress), Twiggy (famous 1960's model who admitted sucking her thumb at age 25), Suzanne Sommers (until her mid 20's), Courtney Love, Andrea Corr (famous singer), Renaud au Zenith, a famous performer, Nina Hagen, Amy Winehouse (deceased, but a public thumb sucker), and many, many others.

yes

A lot of them do. Like Dukey in Jhonny Test

Pacifiers

same reason a child sucks a pacifier they just kinda do it might be to go to sleep or comping method just depends

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.

Depending on the condition of the gums and jaw, usually not. Once the growth stage has finished, usually by age 14 or 15ish, an adult would have to suck their thumb, with sufficient pressure on the dental structures, more than 6-12 hours each day for years to have a remote chance of moving their teeth.

If, however, the jaw bones and/or gums are diseased the chances increase proportionately and would, therefore, react to a thumb sucking force more easily but it would still take quite some time and effort.

Thumb sucking is a common self soothing technique used by babies and toddlers. When children keep this habit through childhood, it could take more than a month to break it.

you will get an over bite

yes u should get that stopped by the age 5

It is estimated that up to 80% of children below the age of 2 suck their thumbs at some point, with from 40-60% developing this behavior as a habit.

I think it is something that soothes them. It is like a child carrying around a blanket. My son is 17 yrs. old and still does it. He does it without realizing it. He will also rub someone else's ears if allowed to do so.

This is a quite normal behaviour for any baby.

Some such their entire fist. Some only a finger or two. some only the thumb.

A very few does not suck their fingers or thumb at all but this is very rare.

Babies are all different. So are we.

The good thing about a thumb is that it is always available :-)

Intense sucking can make it red and sore. Give the baby something else to suck on as well.

Though there are cases of severe adult thumb sucking (usually found in prisons, and places that care for mentally handicapped people) it can't be done non-stop because the individual uses their mouth for eating, etc. There was at least one case where a mentally handicapped woman, age 65, continuously sucked her thumb to the point of actually causing severe skin damage. She was forced to cease in order to allow her thumb to heal. This was achieved by substituting a pacifier, but she eventually started sucking her thumb again.

Depending on the frequency, duration, intensity, and technique plus the general health of your dental structures and your age (if you're in the growth stages of your jaw and dental structures it will have an increased chance of affect) it may, or may not result in the "need" for braces, a situation that depends on your tolerance for any possible resulting malocclusion as well as the opinion of your dental professional.
