This is a bit funny because I have daughters, however, in their infinite wisdom, my one brother and his wife decided to leave their preschool age son with us while they went on vacation. What my brother failed to let me know was that my nephew wets the bed fairly frequently. Thanks, bro! Imagine my first night with my four year old nephew, my toddler daughter, and my baby daughter. Mania. I sent my husband to the store at about one in the morning and he came back with these. Yeah, those Marvel PJs my brother must have picked out were replaced very quickly with the UnderJams and a fresh set of PJs. And I was very lucky, because he wet himself again that same night. These were a must have that week. And...guess what? My brother told me, when he got back from his vacation, that they use these at home all the time...they simply forgot to pack some. Apparently they work at his house, as well. Great to have around if you're expecting a guest.
