DS is 4.5. He was potty trained in the daytime just before his third birthday and has rarely had any accidents, but he is nowhere near being able to sleep without a nappy.
Ever since he stopped wearing nappies in the daytime he has saved his poos for nighttime. This has made us reluctant to even try him without a nappy at night. We sit him on the toilet for a few minutes before bed every night and he gets a sticker for his chart and lots of praise every time he poos in the toilet, but he still does 80% of them in the nappy. It's actually a similar story with weeing - he'll hold it in for hours during the day and refuse to go to the toilet, but in the morning his nappies are always really wet and heavy.
What can we do about this? I feel like we're making no progress and I don't know whether to keep being patient or go cold turkey with a plastic sheet.
