Daughter’s privacy when changing diaper

I’ve been thru the same situation except that it’s my grandma which is easier for my case. I told my dad to leave the room when I wanna change my daughter’s diapers and my grandma told me “aiya you think too much” and I’m like no, please go out. I feel that guys on the other hand should auto abit without the need of anyone telling them to do so, my fil will turn away or leave us alone when he sees me getting diapers. If it’s me, if I already repeated myself so many times, I will just cut the crap, take baby and go into the room. I really can’t be bothered if you’re angsty or unhappy compared to me trying to protect my own baby. Just because she is young doesn’t mean she has to change infront of everyone right.
