My boy will be 4 this month but he still sucks his thumb...is it a matter of concern and how can I change this habit?any suggestions

A. Hello dear parent! Keenly observe your child to understand what is triggering such behaviour like is it attention seeking from anyone, passive sucking, anxiety. Gently probe your baby to know. Try giving alternate latch like frequently hugging your child, few attractive finger toys to keep away the habit of thumb sucking
