Crying over spilt milk (or juice)

I am just sick of stepping into spilt milk/juice. Those non spill cups are frauds. The nipples on Abi's bottles are even worse. I wipe after these kids over 3 times a day. Because of the spills I have banned food or drink of any kind from the bedrooms. Their father has a difficult time adhering to these rules and my mattress is stained with strawberry milk. Want to ban them from anywhere but the dining table altogether. We'll see how that goes.
