Could there be a relationship between bed wetting and caffeine? Since caffeine is a diuretic it seems possible, even likely. Trish, perhaps check with your son and see if he's been having any Mountain Dew lately! Also, my MIL taught me when I was pregnant that keeping the bladder active during the day makes for more rest at night. It worked for me, I only had to get out of bed once at night during my whole pregnancy unlike the first pregnancy when I was having to pee every hour on the hour during the last two months.
