My Peri loves to be naked too even when I take her diaper off it seems like she does everything to keep me from putting it back on. She never fussing but plays around. lol Now I can say this morning I was rushing when I was getting her dressed and she hated it. Maybe make a little game out of it. Peek a boo...behind the clothes or something.
Brady LOVES to be naked or just wear his diaper. It's quite cold here this winter so he always has to wear clothes and such. He will sometimes fuss when I dress him but after a bath or when switching from pj's to clothes for the day...I just give him like 10 mins of naked time. He goes crazy kicking his feet and having fun! He also knows that if he's naked that he gets lotion time and he loves that too!
My youngest sister never wore clothes. Haha, that was FOREVER ago, but it didn't seem to matter back then. Both my boys have always worn clothes. Just remember to dress them the same as you dress yourself. I'd just assume let me kids run naked if they wanted to, but luckily neither like that so far.
Actually this is very common, depending on her ability to understand and how much you want to fight with her, you need to set boundaries and decide when it is and is not appropriate to go without clothes.
It could be that you are dressing her too warm or not enough. Navy will fuss if the temperature drops here at night and she isn't wearing enough. She'll also fuss if she is wearing too much.
