When a child sucks their thumb, they will feel more comfortable. They get pleasure in what they are doing. Also, if you are going to pay attention to babies, you will see that they suck their thumbs if they are scared, hungry, sleepy, or tired.
However, thumb suckers can find their habits up to the age of 6 months. Some people can suck their thumbs or pacifiers until they are 3 to 4 years old. You should start worrying if they continue to do so and perhaps much more intensely after these ages. You can also visit this website to buy thumb sucking guard from the Amazon Australia website.

There are three main issues associated with thumb sucking. First, it has something to do with your physiology. The more you suck the thumb, the more you cause your teeth to become misaligned. Many of your teeth may start coming forward. Orthodontic treatments such as braces don't really come cheap these days, yet you can't avoid them. Otherwise, you can become a target for jokes. It is also possible to suffer from Lisp or other types of speech problems.
Psychologically, people who suck the thumb are often considered emotionally insecure. They cannot find satisfaction or security over other things, so they do what they still did when they were children.
Finally, your hands are unhealthy. Thousands of bacteria can grow in your hands. When you touch your mouth with them constantly, you are also bringing microorganisms inside your body.
The treatments should be performed as early as possible to stop thumb sucking of your children.
