My baby fell off the bed last Monday. The next day he had uneven pupils. I took him to the Dr and they did a CT and it was clear.?

I am worried sick over it. If it has been a week and his pupils are still uneven should I take him back? Everything else seems good but he is only 5 months so it is difficult to evaluate his coordination and of course he doesn't talk so it's impossible to say if he is having pain or anything like that. Is he out of the woods as far as dying? I'm assuming if he was in any danger they would not have sent us home. He never lost consciousness and is very alert, smiling, trying to crawl , reaching for us etc.I watch him while he's sleeping and think "is his hand twitching because of the concussion or did it do that before?" I am trying to evaluate him and eaten up with guilt and can't stop worrying. I'm not sure what to do or if he's ok and just needs time to heal. I asked my husband if he could still die from it and he said "I don't THINK so" and that has me wound up all over again. When are we out of the woods with it? I would have thought we are good by now but, unfortunately, I'm not a neurologist. Before anyone says anything about him falling, please be kind. It was my fault...I turned my back on him for a moment. He has had a recent spurt in movement and I didn't realize how much. I have beat myself up over it and stayed up watching him breathe for the first 3 nights. I am horrified that it happened.
