DS is pee and poop trained during the day. At night he wears a pull up and sometimes it is wet and sometimes dry. He never poops in his pull up at night anymore. However, at what age should I expect DS to be pulling up and down his own underwear and pants? At what age should I expect him to be wiping himself? DS is 3 1/2 and always tells me he can't pull his pants and undies up and down. He will do it sometimes but usually not.
