I'm a lone (male) parent to DD of 3.6. She's been out of nappies at night for about a good month or so now, and a lady of my acquaintance told me she should be wearing knickers at night.
So. Should DD wear knickers in bed along with her pyjamas?
Personally, I can't see any point in it as it's just another thing for her to remember to remove when she uses the potty in the night.
