Can thumb sucking habbit result in reduced appetite in children? What is the best way to stop kids from doing this?

Age and School. Many parents have asked me about thumbsucking. It provides emotional support for the child and yelling only makes things worse. Increasing maturity and peer pressure will solve the problem. Many quit on their own. For the rest, the first time a child sucks his/her thumb in school and gets called a baby will be the last time (S)he does it.. I've never seen it linked to appetite. Hope this helps.
