Hi there ...need not to worry because thumb sucking in children is completely normal till 4years of age ...it has many causes ...major being
1. lack of emotional love and care OR
2. just for pleasure..
But, try to stop your child from this habit gradually, because if it continues ...can lead to many dental and oral problems in future ...
Visit a nearest pediatric dentist for further assistance on this...
Take care ..!!
