1. It is sunnah for one to greet children with salaam. When Nabi (Sallallahu Alaihi Wasallam) would see children, he made salaam to them
وعن أنس قال : إن رسول الله صلى الله عليه وسلم مر على غلمان فسلم عليهم (مسلم رقم 2168)
Hazrat Anas (Radhiyallahu Anhu) reports that on one occasion Rasulullah (Sallallahu Alaihi Wasallam) passed by a group of children, and he made salaam to them.”
