Babies can start sucking their thumbs as early as in the womb, around 15 weeks gestation. After birth, thumb sucking typically begins around 1 to 3 months of age. This behavior is a natural reflex and can provide comfort to infants. Most children will naturally outgrow thumb sucking by the age of 2 to 4 years.
They CAN suck their thumb, however by that age, they should have grown out of it.
Females suck their thumb more than males, especially in the older age groupings, by about a ratio of 3:1 while as the age reduces so does this ratio.
a baby would because all they can do is cry and suck there thumb but leprecons can kick shins
No. But don't suck on your thumb, it's weird.

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.
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.
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.
Babies mostly do
No.
Up to 80% of children under age 2 suck their thumb with the percentage decreasing with age. It is estimated that up to 2% of adults continue the habit, with the highest (unrealistic) estimate at 12%. The largest fall off occurs between the ages of 4-6, with the next fall off occurring at 8-12, slowly diminishing thereafter.
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.
