Kids walking around naked

Hi! So i have a 2 year old .

She has a habit of taking her diaper off , and walking around naked . In the backyard and or in the house . She only does it when she is home .

My fiancé , got upset with me saying it’s wrong. I don’t think it is… it’s innocent . She’s a toddler . I felt attack as if he was coming for my parenting . He said he doesn’t want her walking around naked . Even though she doesn’t do this often , i don’t agree with him because i just feel it’s innocent and random when she does it . Am i wrong ? I feel like i am fighting for her to walk around naked but i don’t feel that way . I just feel he is wrong . Idk 🥺
