3. Cerebral Palsy

And this is seen to start in babies and toddlers. This is actually a rare movement condition which goes away after the baby has been treated for GERD. Sometimes it goes away with time as well.

This syndrome can cause back arching in the babies, which can last for as long as 3 minutes in a frozen kind. Some people may even mistake it for being a baby seizure. This can happen for as many as 10 times in one day with the baby, mostly after having the meal.
