Five-month-olds are on the move, rolling in both directions and pivoting on their tummies. They are beginning to explore cause and effect with great enthusiasm and may sit briefly with support. Baby's curiosity about the world is expanding rapidly and their social repertoire includes both joy and the beginning of stranger awareness.
