best way to clean spilt milk off tiles?

I know it seems like a stupid question but it's baby milk and it smells nasty, I've mopped it but it only make the floor greasy and slippery. It's all over the floor and all over me. I don't want kids because I don't have the patience for this shit yet I have to clean up after other people's kids because they're so fucking lazy and inconsiderate. Never again will I invite people with kids over.
