I don't believe in corporal punishment either, but I do think you can have certain expectations and rules in place and stand firm on them. You can't keep her from taking her own clothes off and going naked in the house but you can tell her we are going out and you need to be dressed, period. Don't present it like it's an option for her to stay home because she doesn't want to wear clothes. She's 2 and you still need to be in charge. I will throw it out there that maybe she has some sensory issues and certain fabrics, tags, etc. may bother her. But she needs to learn that she has to follow the certain rules like being dressed when we go outside, just like she is going to have to follow certain rules everywhere. Maybe you could designate a certain time every day as "naked time" where she gets to run around nude, as long as she keeps her clothes on the rest of the time. Offer her an incentive, like a sticker or M&Ms, for keeping her shoes and socks on in the car. Give her 2 simple choices for outfits and socks and let her pick what she wants.
