Know the symptoms of infantile spasms

Something just isn't right

Parents and caregivers are usually the first people to notice the motions and behaviors that give infantile spasms (IS) its name. Initially, you might think your baby has colic or another routine health problem. However, parents of children with IS often say that "something just doesn't feel right" about the way their baby is acting. There are various infantile spasms causes, and most are not obvious without testing.

What you may see

Spasms usually begin within a baby's first year. They occur most often in the morning or after a nap. They may last from less than a few seconds to up to 10 seconds—and they can happen in clusters of 2 to 100 at a time.

Spasms, which are a type of seizure, involve sudden, uncontrolled movements, including:

  • Bending or bowing from the waist when sitting
  • Nodding or bobbing the head forward over and over
  • Stiffening the neck, trunk, arms, and legs, or extending them out
  • Bringing up the knees when lying down
  • Wrapping the arms across the body like the child is hugging themself
  • Extending or thrusting the arms to the side while elbows are bent

Share what you see

You should record a video of your child's movements to share with your doctor.

For example, a baby with colic may cry, lift the legs repeatedly while clenching the hands, or have a swollen stomach. It's important to speak with your pediatrician about your infant's spasms.

What you should say

You are your baby's advocate. If you are seeing the symptoms of IS, the most important words to say are, "I think my child could be showing signs of infantile spasms." It's OK to be persistent.

When you call to request an office visit—and when you meet with a doctor in the office or the emergency room—there are some ways you can describe what you are seeing in your child that may help your doctor identify what is happening. IS is sometimes misdiagnosed as colic, gastroesophageal reflux disease (GERD), or another condition.

It helps to be specific. Here's a list of possible symptoms, so you can better describe what you're seeing and why it concerns you.
