Quick Answer
If the top of your baby's head moves or pulses, it's usually completely normal. This soft area is called the fontanelle (soft spot) and allows your baby's brain and skull to grow. You're not touching their brain—a tough protective membrane sits underneath. Gentle washing, brushing and normal handling are safe, but seek medical advice if the soft spot becomes unusually bulging, very sunken, or your baby seems unwell.
Why Does the Top of My Baby's Head Move?
The first time I noticed the top of my baby's head moving, I had so many questions.
Was that normal? Could I touch it? Was I actually touching their brain?
If you've spotted a soft, slightly pulsing area on the top of your baby's head, you're not alone. It's something many parents notice but nobody really explains until you ask. In most cases, what you're seeing is a completely normal part of your baby's development.
What Is the Soft Spot?
The soft spot on your baby's head is called the fontanelle.
Babies are born with small gaps between the bones of their skull. These gaps allow the skull to move during birth and give the brain room to grow rapidly during the first months and years of life.
Although it feels softer than the surrounding skull, you're not touching your baby's brain. A tough protective membrane sits underneath the fontanelle, helping protect the brain while the skull bones gradually grow together.
You may also notice the area gently pulsing. This is usually caused by blood flowing through the blood vessels underneath and is completely normal.
As your little one grows, you'll notice lots of changes. If you're wondering what comes next, my Baby Milestones guide explains what to expect during your baby's first years.
What helps: Products I actually used
Gentle Baby Shampoo. A mild, fragrance-free baby shampoo helps clean the scalp without irritating delicate skin.
Hooded Baby Towels. A hooded towel makes it easier to gently dry your baby's head after bath time while keeping them warm.
Baby Bath Support. A baby bath support can help keep your little one secure during bath time, making it easier to wash their hair with confidence.
Can You Touch Your Baby's Soft Spot?
Yes.
Many parents avoid the soft spot because it looks delicate, but normal everyday care won't harm your baby.
That includes:
Washing their hair
Brushing their hair with a soft baby brush
Drying their head with a towel
Gentle cuddles and everyday handling
You don't need to avoid the area completely. The fontanelle is much more protected than it looks, although you should always handle your baby's head gently.

When Should You Get Medical Advice?
Although the soft spot is normally soft, flat and may gently pulse, it's worth getting medical advice if:
It appears unusually bulging when your baby is calm.
It looks very sunken.
Your baby seems unwell alongside changes to the soft spot.
You're worried about any sudden change.
If your baby has other symptoms too, my Baby's First Cold and Common Vaccine Reactions guides can help you understand what's common and when it's worth seeking medical advice.
Final thought
A baby's soft spot can look worrying until you know what it is.
The good news is that it's a completely normal part of your baby's development. You're not touching your baby's brain, gentle everyday care is safe, and the slight pulsing many parents notice is usually nothing to worry about.
Sometimes, understanding why something happens is all it takes to feel much more confident as a parent.
