Ds2 is 4, nearly 5 years old and always wants to be naked. I do suspect some sensory issues, but believe he is otherwise neurotypical. The first thing he does when he gets in from school is strip off. I put him to bed in simple pjs and when he gets up he's naked. I don't want to stifle him and being comfortable with his body, but he is getting to an age where I think it would probably be more appropriate for him to be clothed. We do try to encourage at least underwear but as soon as he can he strips it off and there's his bum again. 🙈 any tips or advice from people who have experienced the same would be much appreciated.
