The Moro Reflex: Your Baby’s Natural “Startle” and Journey to Feeling Secure
That sudden, wide-armed reaction your newborn sometimes has to a loud noise or a slight change in position?

That’s the Moro Reflex, also known as the startle reflex. It’s a normal and important reflex that helps your baby in their early days.
What You’ll Likely See:
When triggered by something unexpected, your baby might:
- Quickly throw their arms and legs out to the sides.
- Their head might briefly tilt back.
- They might take a sharp breath or even let out a little cry.
- Soon after, their arms will often come back towards their body, sometimes looking like they’re trying to grab on.
Why It’s Important:
This reflex is more than just a startle! It’s actually one of their first ways of signaling that they need comfort and security. When you respond by holding and soothing them, you’re helping them learn to feel safe in the world. This reflex also plays a role in their very first breath and helps them develop a sense of their body.

As They Grow:
As your baby’s nervous system matures, the Moro Reflex should naturally become less pronounced, usually within the first few months. They’ll start to react to surprises in a calmer, more controlled way.
