How do you know if your baby has CP?

CP can be different in each child. Some children have mild CP. They may have some awkward body movements and need little or no special help. Other children have more serious CP. They may need a lot of special care their whole lives. CP doesn’t get worse over time, but its symptoms can change.
Some but not all babies with CP often have developmental delays. This means your child doesn't reach developmental milestones when expected. A developmental milestone is a skill or activity that most children can do at a certain age. Milestones include sitting, walking, talking, having social skills and having thinking skills. Tell your child’s health care provider if you notice any of these signs in your baby at these ages:

Younger than 6 months
His head falls back when you pick him up from lying on his back.
He feels stiff or floppy.
He seems to push away when you hold him.
His legs get stiff legs and cross or “scissor” when you pick him up.
Older than 6 months
He doesn't roll over.
He can’t bring his hands together.
He has trouble bringing his hands to his mouth.
He reaches with only one hand while keeping his other hand in a fist.
Older than 10 months
He crawls by pushing off with one hand and one leg while dragging the other hand and leg.
He scoots around on his bottom or hops on his knees, but does not crawl on all fours.
Older than 1 year
He can’t crawl.
He can’t stand up with support.
If you think your baby has developmental delays or other signs of CP, talk to her provider. Diagnosing CP usually happens in three steps.
Developmental monitoring. Your baby’s provider checks her growth and development over time. If your baby shows signs and symptoms of CP, her provider recommends developmental screening.
Developmental screening. These tests check for developmental delays, like problems with movement. The American Academy of Pediatrics recommends that all children have developmental screening tests during their well-baby visits at 9 months, 18 months and 24 or 30 months.
Developmental and medical evaluations. If results of your baby’s screening tests aren't normal, your baby’s provider recommends developmental and medical evaluations. These can be done by your baby’s provider or by a child neurologist. This is doctor with special training in treating brain conditions in babies and children.
Your baby’s provider also may recommend these tests for your baby:
Blood tests
Computed tomography (also called CT scan). This test uses special X-rays to make a picture of your baby’s brain.
Electroencephalogram (also called EEG). This test records electrical activity in your baby’s brain. It can help diagnose epilepsy, which sometimes happens in children with CP. Epilepsy is a seizure disorder that affects how the nerve cells in your brain work.
Magnetic resonance imaging (also called MRI). This test uses radio waves and magnets to make a picture of your baby’s brain.

Ultrasound. This test uses sound waves to make a picture of your baby’s brain.
