What can I do at home for my baby's flat head?

What is not on this page is stretching. You will find neck stretches for babies all over the internet, complete with timings. We are not going to give you those, because the direction of the stretch depends on which side is tight, that is something only a hands-on assessment can establish, and stretching the wrong way can make things worse. If your baby favours one side, that is a reason to book a paediatric physiotherapist, not a reason to follow a video.

Because flattening is caused by sustained pressure in one spot, and pressure is the thing you can change. The skull does not squash. It grows outward in response to the brain expanding underneath it, and where that growth meets a resting surface it is resisted, so the extra volume goes elsewhere. Take the pressure off that spot regularly and new growth is no longer being resisted in the same place. How much that changes the shape varies from baby to baby, and nobody can tell you in advance which way yours will go, which is why you photograph and check rather than assume.

This is where The Perfect Noggin fits in: a contoured head shaping surface that redistributes pressure away from flat spots while your baby sleeps. It complements the repositioning habits above rather than replacing them, and works alongside your physiotherapist's care rather than in place of it.

Timing matters more than effort. Skull growth is fastest in the first four to six months, so the same habits applied at three months do considerably more than at nine. That is not a reason to panic if your baby is older, and it is not a reason to overdo it if they are young. It is a reason to start now rather than next month. Our timing guide covers what is realistic at each age.

It is also worth being clear about what these habits do and do not do. NSW Health lists infant handling, counter positioning, stimulation of motor development and parental education as having strong evidence behind them⁵, so this is not busywork. What they do is stop flattening getting worse. What they do not do is undo flattening that has already formed, and they are only really possible while your baby is too young to move themselves. On top of that, where neck tightness is driving a head preference, repositioning alone usually will not shift it, because the pull is coming from the muscle rather than the room.

Australia's 24-Hour Movement Guidelines recommend at least 30 minutes of tummy time spread throughout the day while your baby is awake, for babies who are not yet mobile.¹ Two things in that sentence matter as much as the number. It is a daily total rather than one session, and it applies while your baby is awake and supervised.

If you have a newborn, do not try to hit that today. The Royal Children's Hospital suggests starting with one to two minutes and building gradually, working towards ten to fifteen minutes about three times a day by around four months.² That is the same destination, reached at a pace a small baby can actually manage.

Frequency beats duration. Several short goes across the day are easier on your baby and easier on you than one long session anybody dreads. RCH suggests tummy time works best when your baby is awake, not too tired, and not straight after a feed.²

Plenty of babies object at first. Two things that help: lie back and put your baby chest to chest with you, or drape them across your lap during a nappy change. Both count. So does putting yourself, rather than a toy, on the side your baby finds harder to look toward, because your face is the most interesting thing in the room and it gives them a reason to turn that way.

Tummy time is always supervised and always while your baby is awake. Never leave your baby on their tummy to sleep.

Small, repeatable changes, made often. None of these is dramatic on its own. Together they change how many hours a day the same patch of skull is bearing weight.

• Alternate which end of the cot you lay your baby down at. The room does not change, but which way your baby has to look to see the interesting part of it does.
• Alternate which arm you feed from. If you are bottle feeding, swap arms at every feed. Breastfeeding does this for you.
• Vary how you carry them. Swapping shoulders through the day, and carrying your baby face down along your forearm, both take weight off the back of the head entirely.
• Cut down time resting against a flat surface. Car seats, capsules, bouncers, swings and rockers all put the back of the head against a flat surface. Use them when you need them, and swap some of that time for floor play or a carrier where you can.
• Approach from the less-preferred side. Come into the cot, and start conversations, from the side your baby turns away from.

Consistency over intensity. Several weeks of ordinary, imperfect effort does more than one determined afternoon. If you miss a day, start again the next morning.

Sleep is where most of the pressure accumulates, and it is also where the least is safe to change. Always place your baby on their back to sleep. That is the foundation of safe sleep guidance in Australia and it does not change because of a flat spot.

Red Nose Australia recommends a clear sleep space free of pillows and loose bedding⁹, and states that products which restrict the movement of a baby or a baby's head should not be used.¹⁰ The Royal Children's Hospital similarly advises against using a pillow during sleep to prevent or manage flattening, because of the risk of sudden infant death syndrome.³

Where does Perfect Noggin sit in this?

Fair question, given this is our site and Perfect Noggin is used in the cot. Here is the distinction, and where it stops.

Perfect Noggin is not an item added into the cot alongside the mattress. It is a firm, single-piece surface with nothing loose, nothing soft to sink into, and nothing holding your baby's head in place. Your baby lies on their back and their head stays free to turn. That is different from a pillow, a wedge or a positioner, which is what the guidance above is describing. Here is where it stops. Once your baby rolls from back to belly, stop using it. That is a safety boundary rather than a preference, and most babies get there somewhere around four to five months.

Then repositioning on its own is unlikely to be enough, and that is the single most useful thing to know on this page. Fenton and Gaetani report congenital muscular torticollis in up to 70 to 95 per cent of infants with deformational plagiocephaly.¹² If your baby keeps returning to the same side however you lay them down, the neck is the first thing to get looked at.

The Royal Children's Hospital notes head shape typically improves once torticollis is treated.³ That is why an assessment beats persistence: you are not failing at repositioning, you are working against a muscle. Our guide to torticollis covers what to look for and what an assessment involves.

A physiotherapist will give you a programme specific to your baby, including any stretching, with the direction and the technique shown to you in person. That is the right way to get it, and it is why those instructions are not on this page.

Give it four to six weeks of consistent effort before judging it, and photograph your baby's head from directly above every two weeks, in the same spot and the same light. Day to day you will see nothing. Two photos a month apart show you what is actually happening.

If there has been no visible improvement after four to six weeks, or the flattening is more than mild, or your baby has a clear side preference, book a paediatric physiotherapy assessment rather than giving it another month. That is not a failure of the home approach. It is the point at which it needs professional input alongside it. For what to expect week by week once you do, see How long does a flat head take to improve?

Not every unusual head shape is positional, and the habits on this page are for the ones that are. Some head shapes are caused by craniosynostosis, where the joints between the skull bones fuse too early. That needs medical assessment rather than repositioning, and it should not wait out a six-week trial at home.

When to seek medical assessment for your baby's head shape covers the warning signs in full.

Start the positioning changes and the tummy time today, because neither needs an appointment or a purchase. Then book a paediatric physiotherapy assessment, particularly if there is any side preference. Your GP or child and family health nurse can refer you, or you can book directly with a clinic.

If you are not sure what you are looking at in the first place, the four-point check walks through it in two minutes. If you want the full picture of what changes at each age, the month-by-month guide covers birth to twelve months.
