K.D.
My oldest son also had an issue with bedwetting. He was 'daytime' potty trained by 2.5 and was about to start kindergarten while still wetting at night. I was very upset and felt like I failed at this stage of parenting because everyone else his age (it seemed) was completely trained.
I brought it up to his pedi, and told him how we were wakng him at night with no avail.
His suggestions-do NOT wake him at night. You're not actually teaching him anything. His body needs to get the signal himself. (I didn't like that suggestion at all). Secondly, and most importantly, he'll be ready when he's ready. I got him back into the pull-ups with different tactics (mostly, he just didn't want to keep waking up wet and was not a fan of helping me change the sheets at 2am), and put a protector on his bed. He didn't earn special rewards for keeping dry, just a neutral 'good job, keep it up'. He can't control the bedwetting. His body will be ready when it's time.
Hang in there-it'll fix itself soon!
