Mommy rep destroyed

So it happened and it happened today my 6month old proved to mom he can't be trusted on couch he tumbled right off I ran n found him crying laying on his back .he had a red mark on his right eyebrow and a red mark on his left knee making me think he fell sides and then flipped over somehow ..ugh the not knowing is killing me I'm trying not to beat myself up about it alot of moms say it happens to the best of us ..I was literally setting up so I could feed him all I needed was a spoon and I took the leap to grab it n regret it completely ..I consoled him forever he quick crying after a min or so but I couldn't let him go I literally felt like wowww why would I even try but i can't say it was the first time me doing that i usually would put in far in the corner n distract him with a toy or something but wow that method is a big mistake i should know better being my background is working with kids ugh I can't believe mommy cause the first fall ..I checked him from head to toe all limbs and head for bumps none at all I make sure he didnt develop fever or cranky or lethargic.. huge note to self NEVER DO THAT AGAIN BRING BABY WITH U ..I jus can't believe it hearing the thump I was like omg omg no no no ..so basically here's a lil question 'Has ur baby fallen off anything under ur care, what was it and how high? How did u respond?.
