DS1 is 4.3 and has been potty trained since he was about 2.5yo, but he still wears nappies at nighttime.
His nappies are very heavy in the morning. He's given no indication of wanting to stop wearing them and he still has a cup of milk at bedtime before books and teeth.
Am I right in thinking that there's nothing you can do to 'train' them to be dry at night?
