sweet daughter

What do you say to your child when they just want to eat dinner naked!!!
I mean it is a great expression of freedom and I love that my five-year-old loves
to be naked but suddenly I might have a thirteen-year-old boy wanting to do the same and
I think dinner might turn into anarchy even for our family!!
So I pose the question again, What do you do when your 5 year-old wants to eat dinner
naked??? Because my answer caused a huge flood of tears, luckily she recovered in about 15 minutes.
