Supervised tummy time is important. Because babies spend so much time sleeping on their backs, it is important to provide exercise time for them to strengthen their upper body muscles (neck, arms and chest). This should be done while they are awake and being watched. Lots of tummy time will also help prevent a flat spot from forming on the back of your baby’s head. Start by placing your newborn across your lap for short periods of time, gradually working toward placing them on a quilt or play mat on the floor with toys in front of them. This is also a great way to spend quality time with your baby – playing together on the floor! Watch for signs that your baby is tiring and change their position or activity. If your baby falls asleep during tummy time, immediately place him on his back in his crib for a nap.
