Help!

My 8 month old fell face first this morning and I feel so guilty ! He had a bloody nose (I didn’t notice until now) and it’s all red on the side of the nostril. Our bed on on the floor due to moving. I looked away for a second and all I hear is him crying face first on the floor. He was hysterical for 5 mins and then fell asleep ...

I don’t know what to do.

He seems okay, he’s napping now again
