6 month old mild spastic cp

Hello my 6 month old was recently diagnosed with mild CP of 1-3 limbs. He is on time with his milestones and hasn’t fallen behind. The only reason it was noticed was because I noticed some stiffness at times in his legs. I am beyond devastated and truthfully having a hard time accepting this. He was a delayed c section… resuscitated at birth with a double cord wrap. Can any parents tell me how they new there baby had CP? HisEEG is normal. We are doing a MRI soon. Also what will his life look like? I am terribly nervous he may not have any chance of a normal life. What’s wild to me is he is very advanced with his motor skills. He was crawling at 5 months.
