Hi Tetro, I'm in the same situation. My son will be turning 3 in a couple of days. He is potty trained during the day and through his nap but he's not ready for night time. His diaper is still wet in the morning. We just moved him into his toddler bed (but he hasn't figured out yet that he has the power to get out lol). Sometimes he'll call out and say he has to pee and we bring him during the night, but most of the time he continues to pee in his sleep. We'd like to wake him up during the night to take him to the bathroom but as soon as we wake him he is WIDE awake. And then it's a problem getting him to go to sleep. I really don't think he has a bladder infection though. What we've been doing is cutting back his liquids at night, which hasn't been too difficult. He was using the big sippy cups but he would treat them as if they were bottles....he would just chug and chug it down. I found if I gave him something to drink in a normal cup he would just take sips out of it every now and then.
Anyway, let me know if you figure it all out.
I'm very impressed that your 2 year old is trained! My son took a long time. I hear boys do that though. Duh...no surprise.
Good luck,
Meg
