Pee and more pee

I am so freakin' tired of all this bed wetting! Pumpkin is not potty trained but we had solved the pee leaking out of her diaper. It's been 3 consecutive mornings, plus other random ones that I need to wash sheets and try to control the urine odor. Anyone has a good idea of getting this done? Her mattress in new and stained, with some smell. Unfortunately, of the 3 days, 2 included my bed because she headed to our room in the wee hours of the morning. Nothing like rolling over in your bed and landing on a cold pee spot to start your day.
