Is this bad? She's 2 (27 months, so the young side of 2). I can't keep clothes or a pull up on her to save my life so I usually just let her run around naked. She uses the potty about 75% of the time but does occasionally have accidents. Luckily we have laminate flooring so it's easy to clean up. There's carpet upstairs but she only has accidents up there maybe once a week because she's downstairs most of the day.
I do dress her when I'm expecting company and before DH gets home from work, but I can't say the UPS man hasn't seen my nekked little girl standing at the window beside the door lol. I make a point to dress her every morning but she usually takes it off.
