Tummy time:
what the institutions write.
Five bodies: one says at least 30 minutes, two say 15–30, two give no minutes at all. They agree on one thing: awake and supervised. We report all of them with their sources — without picking one.
Important: This page contains general information and is not a substitute for medical advice, diagnosis or treatment. Beluna is a recording tool; it does not suggest target minutes and does not assess a baby's development. Any concern about a baby's motor development or head shape belongs with the health professional who follows you and your baby.
Every statement here comes from the bodies in the References section: the WHO, AAP, NICHD, NHS and BIÖG. The page reports what they write; it does not pick one and does not turn any of it into advice.
The durations the institutions write
Tummy time is time a baby spends lying on their front while awake. We put side by side what the institutions publish in answer to “how much a day?”; the wording belongs to them.
| Body | What it writes |
|---|---|
| WHO (2019 guidelines) | For infants under 1 year who are not yet mobile, at least 30 minutes in prone position spread throughout the day while awake. |
| AAP (US) | At first 2 to 3 times a day for a short time (3 to 5 minutes); increased as the baby shows they enjoy it, working up to 15 to 30 minutes a day by 7 weeks. |
| NICHD Safe to Sleep (US) | Two or three short (3- to 5-minute) sessions a day; by about 2 months of age, 15 to 30 minutes of total tummy time daily. |
| NHS (England) | No minutes. It writes that tummy time can start from birth with the baby lying on a parent's chest, that the time can be increased day by day, and that the floor can follow when the baby is ready. |
| BIÖG (Germany, formerly BZgA) | No minutes. It describes placing the baby alternately on the tummy and on the back while awake. |
The bodies do not agree on minutes: one says at least 30, two say 15–30 between week 7 and month 2, and two give no minutes at all. The scope also differs: the WHO's 30 minutes are written for infants under 1 who are not yet mobile; the AAP's and NICHD's 15–30 for the first two months.
This page does not pick one of these durations and does not turn any of them into advice. We report what each body writes, with its source.
Common ground: awake and supervised
Bodies that differ on minutes write the same thing on one point:
- The WHO defines tummy time as time an infant spends lying on their front while awake, with unrestricted movement of limbs.
- AAP: tummy time is for babies who are awake and being closely supervised.
- NICHD: placing the baby on their stomach while they are awake and someone is watching them.
- NHS: for tummy time on a parent's chest, it specifies a time when the adult is wide awake and unlikely to fall asleep.
- BIÖG: writes the tummy-and-back alternation for when the baby is awake.
Sleep is a separate matter: the AAP writes that healthy babies are safest sleeping on their backs, at night and for naps. The NICHD notes that tummy time does not directly reduce the risk of sudden infant death syndrome, but is important for growth and development.
When it starts
- AAP: it can start the day the baby gets home from the hospital.
- NICHD: most babies can start tummy time sessions a day or two after they are born.
- NHS: from birth, with the baby lying on a parent's chest.
- WHO: refers not to age but to mobility: infants under 1 who are not yet mobile.
The reasons the institutions give
- WHO: the guidelines give this as a “strong recommendation” and list the benefits as improved motor development and a reduced likelihood of deformational plagiocephaly (a flattened area of the head). The evidence summary states that, under 1 year, 30 minutes a day in prone position was favourably associated with health indicators.
- AAP: it helps babies build strong muscles and the skills they need to reach developmental milestones.
- NICHD: it strengthens neck, shoulder and arm muscles, improves motor skills and prevents flat spots on the back of the head.
- NHS: it builds upper body strength, strengthens the back, neck and shoulders, and gives the baby a different view of the world.
Prams, bouncers, screens
- WHO: infants under 1 should not be restrained for more than 1 hour at a time (prams or strollers, high chairs, strapped on a caregiver's back); screen time is not recommended; when sedentary, reading and storytelling with a caregiver is encouraged.
- BIÖG: writes that baby bouncers should be used only in moderation and the baby not left in them for long; it adds that prams, high chairs and car seats restrict movement when overused.
- AAP and NICHD: in the context of flat spots, mention limiting time in car seats, swings and bouncers, where the back of the head rests against a surface.
What Beluna does — and does not do
On Beluna's Activity screen, tummy time is recorded with a timer; the day's total minutes and the day's timeline are shown.
Beluna shows no target minutes, draws no ring to fill, does not say “enough today” or “not enough”, and sends no tummy-time reminder. The table above shows why: the bodies themselves do not give the same number.
A record shows your own day back to you. It does not compare it to a number.

Beluna does not impose target minutes
Tummy time is recorded with a timer; the day's total and timeline are visible on one screen.
Beluna gives no medical advice, makes no diagnosis, and suggests no target or schedule.Frequently asked questions
How much tummy time a day?
The bodies write different things. The WHO says at least 30 minutes spread through the day for infants under 1 who are not yet mobile. The AAP writes 15 to 30 minutes a day by 7 weeks, the NICHD 15 to 30 minutes of total tummy time daily by about 2 months. The NHS and BIÖG give no minutes.
When does it start?
The AAP writes that it can start the day the baby gets home from the hospital, the NICHD that most babies can start a day or two after birth, and the NHS that it can start from birth with the baby lying on a parent's chest.
My baby does not like being on their tummy.
The AAP writes that some babies may not like the position at first. The NHS says this is very normal for lots of babies and lists options such as lying the baby on a chest or lap, putting toys within reach, talking and singing, and a small rolled-up towel under the arms.
Can a baby sleep on their tummy?
The bodies write tummy time for an awake baby. The AAP writes that healthy babies are safest sleeping on their backs, at night and for naps; the NICHD writes that tummy time does not directly reduce the risk of sudden infant death syndrome.
What is said about time in prams and bouncers?
The WHO writes that infants under 1 should not be restrained for more than 1 hour at a time in prams, high chairs or carriers. BIÖG writes that baby bouncers should be used only in moderation.
