Thumb sucking is a form of non-nutritive sucking, which refers to any sucking action that is not used to eat and drink. Babies and young children usually suck their thumbs as a way to soothe themselves and feel calmer. Non-nutritive sucking has even been found to provide pain relief during medical procedures. This usually involves a pacifier.
How Long Does Thumb Sucking Last?
Thumb sucking is a common habit that usually lasts until children are between 2 and 4 years old. Each child is different, so consider talking with your healthcare provider or pediatrician if you are concerned about your child’s habits.
When to Stop Thumb Sucking
While thumb sucking is a common habit for babies and toddlers, it may lead to problems if continued for too long. Thumb sucking changes a child’s teeth and mouth over time. For this reason, it is recommended that children stop sucking their thumb by the time their adult teeth are coming in, usually around age 5 or 6.
