Gerber also makes plastic covered underwear that you can put over regular underwear. My son went through the same thing at late 2/early 3. Putting him to bed in underwear (no diaper/pull-ups/etc) worked for us. He would wet the bed, but we just worked through it. Then, he started to not wet the bed, but would wake with wet underwear. We made sure he had his water, went to the bathroom, slept, and then IMMEDIATELY rushed him to the bathroom in the morning. He rarely has an accident.
