A “flat head baby” usually has a condition doctors call positional plagiocephaly<\/em> (say: play-jee-oh-SEF-uh-lee<\/em>), also known as flat head syndrome<\/em>. It simply means one part of your baby’s head has become flattened from pressure on the same spot over time.<\/p>\n\n\n\n A newborn’s skull is soft and made of separate bone plates. This softness is a good thing; it lets your baby’s head pass safely through the birth canal and gives the brain room to grow quickly. But it also means the skull can be gently molded by steady pressure, such as resting on the same spot again and again.<\/p>\n\n\n\n Flat head syndrome is very common. Research suggests that it affects nearly half of all babies to some degree, and most cases are mild. Importantly, this kind of flattening does not harm your baby’s brain, development, or intelligence. It changes the shape of the head, not what’s inside it.<\/p>\n\n\n\n You may first notice flattening when your baby is around 6 to 8 weeks old. Look at the top of your baby’s head from above, and check for:<\/p>\n\n\n\n Some babies have flattening only on the back of the head (from lying flat), which can make the head look wide and short. This is sometimes called brachycephaly<\/em>. Others have flattening on one side, giving the head a slanted, parallelogram-like look.<\/p>\n\n\n\n Flat head syndrome comes from steady pressure on a soft, growing skull. The most common reasons include:<\/p>\n\n\n\n Back sleeping-<\/strong> Babies spend many hours a day on their backs, and for very good reason, sleeping on the back is the single most important way to lower the risk of sudden infant death syndrome (SIDS). Always keep placing your baby on their back to sleep. Flat spots are a manageable trade-off; SIDS prevention comes first.<\/p>\n\n\n\n Time in gear-<\/strong> Car seats, swings, bouncers, carriers, and strollers all keep a baby’s head resting against a surface. Long stretches in these add up.<\/p>\n\n\n\n A favourite direction-<\/strong> Many babies naturally turn toward a window, a light, or the centre of a room. Resting on the same spot night after night flattens that area.<\/p>\n\n\n\n Tight neck muscles (torticollis)-<\/strong> If the muscles on one side of the neck are tight, your baby may struggle to turn their head both ways and keep resting on one side. Most babies with flat head syndrome have some degree of this, and it is very treatable.<\/p>\n\n\n\n Being born early-<\/strong> Premature babies have even softer skulls and often spend a lot of time lying still during hospital care, which raises the chance of flattening.<\/p>\n\n\n\n A snug fit before birth-<\/strong> Twins, or limited room in the womb, can press on a baby’s head before they are even born.<\/p>\n\n\n\n Many parents quietly blame themselves, so let’s put this to rest: a flat spot is not a sign that you did anything wrong. It is the natural result of caring for a baby the way you are supposed to, laying them down safely on their back, holding them, and letting them rest. Soft skulls flatten easily, and that softness is exactly what protects your baby during birth and lets their brain grow.<\/p>\n\n\n\n You did not cause harm by following safe-sleep advice, and you are not neglecting your baby by having a busy day where they spend time in a car seat or swing. Flat head syndrome is common precisely because good, protective parenting habits happen to involve back-lying. What matters now is simply adding a few small habits going forward, not looking back with guilt.<\/p>\n\n\n\n This is the question on most parents’ minds, so let’s be clear. A gradually appearing flat spot that improves with position changes is almost always harmless positional plagiocephaly.<\/p>\n\n\n\n You should call your paediatrician if you notice any of the following:<\/p>\n\n\n\n These signs can occasionally point to a rarer condition called craniosynostosis, where the skull bones fuse together too early. This is uncommon, roughly 1 in 2,000 to 2,500 babies, but it needs medical care, so it is worth ruling out. The good news is that your paediatrician can usually tell the difference at a routine visit, and you don’t need to diagnose this yourself.<\/p>\n\n\n\n Here’s a simple side-by-side to help you understand what your doctor is checking for. This is for background only, leave the actual diagnosis to a professional.<\/p>\n\n\n\n<\/a>What does a flat spot look like?<\/strong><\/h2>\n\n\n\n
