My kids have 4 sets, but we don't have a washer/dryer and have to get to a laundromat to do laundry, so I can't just throw sheets in the wash right off the bed if they have an accident. My older daughter night trained on her own about a month after day training and has had very few accidents, but there have been a few.
I also will never forget one night when I was a kid. My sister and I had bunk beds, I was on the bottom bunk. I woke up around 1 am and threw up all over. My mom got me cleaned up, got me fresh bedding, took care of me, finally got to sleep about an hour later. Around 3 my sister woke up and threw up. Since she was on the top bunk my mom had to clean both of us up and change both of our sheets! Because of that I keep an insane number of sets of sheets around lol!
lucylea:We've only ever had two sets for DD and I've never used more than that.
Us too, and DD has been fully PT for a while.
2 sets and lots of waterproof pads. We have two mattress protectors that are waterproof and a bunch other ones.
When DS is sick (pukes) I line the couch with that and just was pads instead of sheets.
