Son Potty trained...now started wetting the bed.? - bed wetting store promotion code

Hello! My son, 3 1 / 2 glass has been about 6 months training. He had no problems going to the toilet, with the exception of a few accidents, if we are in a store or a bathroom a place that is not as fast as possible.
Well, last week, he wet his bed. Before, it was only the bed twice in the last 6 months ... But about a week and a half before bed-wetting and lasted all night.
I have a shower curtain I have plastic on the bed ... with a piece of cloth, carry, wash every morning. It is not so clean, the bed, which worries me.
I do not know if I have to buy pull-ups at night, because everyone I spoke, said, no, I'm back ... I wonder if I should.
I cut the liquids two hours before bedtime, but you give sips if he is thirsty. I go to the bathroom right before bedtime ... and wakes up in the middle of the night so he can go. I do not know what I do now. Help!
