Why is your 2 year old licking everything?

A 2-year-old may lick everything out of curiOSity and to explore their environment. At this age, children are often using their senses to learn about textures and tastes. Additionally, licking can be a comforting behavior, helping them cope with anxiety or boredom. It's a normal part of development, but it's essential to ensure they are safe and not licking harmful objects.
