My son is still in pull ups at night, he's 5yrs 6months. He's never once been dry in the morning. He's been potty trained in the day time since about 3.5 but only recently started pooing on the toilet and not in his pull up. We've tried restricting fluids in the evenings but still soaking pull up in the morning. We've tried putting a potty in his room but he doesn't wake up. He sleeps 7pm-7am. Is this normal? I don't know when it's something to be worried about.
