Cerebral Palsy is non-progressive, but why to waste time by indulging in various therapies.
You can expect best results till 5-6 years of age, beyond that rate of improvement decreases drastically.
So start working on rehabilitation of your child from day one, wasting time on isolated symptom is just a waste of time.
You can expect much more from your child, they become independent if allowed to grow in the right direction.
Most of time parents are unaware about the basic requirements of their child and unable to take an appropriate treatment on time.
So always try to take maximum out of your child instead of focussing on unwarranted treatment approaches.
Start early rehabilitation instead of wasting golden period. Early comprehensive rehabilitation is the only cure for your child.
