Thumb-sucking is very common in babies and toddlers. For babies, it is a natural instinct and most babies stop around the age of six months as they learn to occupy their time playing and doing other things. Some children continue to soothe and comfort themselves and they may need a little help to stop the thumb-sucking habit.
Most pediatricians will encourage you to curb your child’s thumb-sucking because it can cause problems later on. One of the biggest problems is that it can cause dental problems that will need correcting. A child who sucks her thumb may cause her teeth to develop at an outward angle (also called malocclusion) and in severe cases, it can cause problems with the upper palate. Sometimes, these problems correct themselves when the child stops the habit, but children that cannot stop will probably need orthodontics. Other problems associated with thumb-sucking include speech development problems and skin irritation on the thumb.
As a parent you will want to help your child stop this habit. There are many things you can do to help your child that are recommended and effective. One common treatment is putting a product on your child’s thumb, such as Bitter Apple, or Thum. This will taste bitter when your child puts his or her thumb in the mouth. Sometimes this is not enough and you will want to combine this with some type of reward system for your child, such as a chart or a rewards calendar.
Another option for children that continue to suck their thumb is to place gloves or bandages on the thumb. This should not be used as a punishment to your child, but as a reminder that thumb-sucking is a "no-no."
Your dentist may be able to help stop the thumb-sucking, too. There are retainers and guards that can be made to fit your child. Many dentists will recommend wearing these devices only when the child has the most problems with thumb-sucking, such as at night or during "down" times when the child may feel bored. These are quite effective in stopping thumb-sucking.
A hand guard is also widely available and may help stop your child. There is no prescription needed. This guard is a plastic device that fits over the thumb and makes it difficult, if not impossible, for the child to suck the thumb. It is also hard to remove, which is a plus for children who are determined to suck the thumb anyway. These are about $50.
You can help your child stop sucking his or her thumb. If you have tried several methods and nothing seems to work, consult your pediatrician.
