Hi D.-
My son just stopped wearing pullups at night last May which was the end of 1st grade for him. My daughter also stopped in May and she started kindergarten this fall. Certainly there were more in 1st grade trained then not, but my son was not the only one. When they started keeping the pull up dry at least 50% of the time, we went without the pullups and then after a couple of wet nights they started staying dry. My son has not had a nighttime accident in a long, long time and my daughter probably has one a month still.
I know other parents who have done the "waking them up to pee" at night thing but I don't understand it. You don't really want them waking up to go to the bathroom in the middle of the night, you want them sleeping through the night. Until their kidneys and bladder are ready to do this, it's just too soon. My suggestion is to wear goodnights each night and once he is staying dry try going without it.
Good luck,
K.
