Just changed my ds's nappy on a change mat at the end of my bed. He rolled off of the change mat as usual - but before I'd had a chance to wipe - so a smallish spot of pee was left on the sheet. It's 2 in the morning and I'm shattered as usual. As he co-sleeps and I want to get him back to bed asap I sprayed with some disinfectant and vigorously wiped then dried with a fan heater. I feel like a complete tramp! AIBU to not change the sheet???
