Re: At what age?
DD was day-trained except for naps by 2 1/2 years old. As in, she could tell me that she had to go pee and then would do it. She'd wait for a naptime or bedtime diaper to poop for a few months but had stopped that by 33 months. Started waking up dry from naps about a month or two after that, then was completely trained even at night within a month or two after her 3rd birthday.
