BEST CHILD SPECIALIST ! Thumb sucking is a natural reflex for human infants, chimpanzees and other primates. In fact, based on the photographs of embryos in the womb, the sucking response begins before we are even born. It is believed that sucking on thumbs, pacifiers or other objects make babies feel secure. This reflex seems to offer comfort and after they are born, reduces anxiety and helps induce sleep. Don’t panic. Most thumb sucking will end on its own without any drama or intervention. Sometimes the best way is to simply ignore the behavior. Peer pressure will often prompt your child to discontinue thumb sucking without a word.
