What to do with this activity?

When a baby is 4 or 5 months old they discover how to roll from a tummy-down position onto their back. Later they will be able to roll from their back onto their tummy. Every child is different - they'll roll over when they are ready! 

It's important to know that young babies should sleep lying on their back. But when they are awake, give them a little time on their tummy. Start with just a few minutes, and don't leave them unattended. Spending time on their tummy will help to build strength in the baby's neck and back - preparation for that roll. When they are ready, lay them tummy down on an activity mat on the floor. Encourage them to lift their head and reach out for interesting toys. If you want to know more, here's a video from the American Baby Center that tells you more about tummy time (it's around 6 minutes long). 

As your baby turns into a toddler, they will enjoy rolling down gentle grassy slopes in your local park. At home, you can create a gentle slope with a small mattress and cushions. Find out what else can roll down the slope - a ball, a toy with wheels, or teddy. Talk about which item rolls fastest and why.
