One of the reason for cerebral palsy is indeed a brain damage, and in your daughter's case the brain bleeding had caused that.
Her symptoms are suitable for this diagnosis.
Epilepsy, often, appears in children with cerebral palsy.
Although, children with CP are usually slow to reach developmental milestones, they can still have normal or even above average intelligence.
Their ability to express their intelligence may be limited by difficulties in communicating.
Because of this, is very important for CP child to get appropriate physical, occupational, and speech/swallowing therapy.
And the last, the answer to your question if there can be a mild case of CP, is yes.
Actually, CP can be in forms that are very mild and subtle to very profound.
This condition doesn't get worse over time.
Best wishes to you and your family!
