Baby cut his face

Hi guys. I feel so horrible. My baby cut his face with his nails. I have been waiting on my husband because last time I cut them, I cut a little bit of his skin. It wasn't tragic but to him it probably was. So his face is cut and I feel so neglectful. I shouldn't have been scared. This could have been avoided. Plus my husband is furious with me. Anyways, he has a scratch and he bled a little, it's a little bit red. How do I treat it?
