Young babies should sleep on their backs but, at playtimes, it's safe and fun for a baby to spend time on his or her tummy.
It's exciting for a baby, and gives them the chance to use different muscle groups as they learn to control their head and limbs, get set for crawling, and start to reach out for objects.
How CBeebies can help
All you need for a bit of fun tummy time is a space on the floor or a rug on the grass.
Don't forget the most interesting person for your baby is you! Seeing your face or hearing your voice will keep most babies happy for a few minutes. You can smile, pull funny faces or blow raspberries, or maybe sing some of your favourite CBeebies songs.
Click through to the Song Time section of the website and take your pick. Maybe choose one which has some hand or dance movements too. Your baby will love being entertained by the sight of you singing and acting out the song!
How to make a magic moment
The most important thing is probably to make sure your baby has some face-to-face contact at the beginning of tummy time.
This is easy if you're balancing a newborn baby on your tummy and chest but, with older babies, you may need to go down to floor level so they can see you smile.
Sing their favourite song (or yours), crinkle an empty crisp packet to make a noise or pull some silly faces and see if you can get a gurgle or grin of delight!
