My 13 week old infant fell off the recliner!!!! I feel horrible.?

I had just changed his diaper and sat him on the recliner to wash the Desitin off my hands so I could nurse him. I walked away turned on the water and THUMP....CRY!!! It sounded like an encyclopedia fell to the floor. I ran out the bathroom and there he lay screaming his head off. He had rolled forward, I think, and some kinda way landed on his back. I WAS SOOOO scared I didnt know what to do, so I call my mom and she came over right away. I felt his soft spot and it was throbbing and I couldnt remember if it pulsated before or not! He cried for about 5 mins and really just wanted to be comforted so I nursed him. He was fine after that and was back to his old fun loving self! I feel SO bad though. I didnt tell his dad. Cause he tells his mom EVERYTHING!!!! *sigh* I digress. But do you think my baby is okay??? No brain damage right????
