Oh yeah, no kidding on that. I went through that with my oldest. First trip in a tent he threw up after the sun went down. Spent all night in a cold car...lol. Backpacking went great, then he had an accident (thankfully just pee) middle of night. I think he had gotten too cold and didn't wake up in time. Got him dried up and we slept under bag, quilt style. Was a cold night for both of us...but we were OK. Thankfully his bag was synthetic, cleaned easily.
