This document provides guidance on tummy time positioning strategies to develop strength and head symmetry in young babies. It recommends incorporating supervised tummy time into babies' daily routines from the first day to relieve pressure on the back of the head and strengthen neck muscles. Suggested tummy time activities include placing babies on their tummies during diaper changes, dressing, bathing, and interacting with caregivers and siblings on the floor. The document warns against excessive time in hard baby carriers and holding positions that apply pressure to babies' heads.
