Am I being weird about diaper changes?

Li

So my husband's parents came over today to visit us and our 3 week old baby boy. While getting ready for bed, my husband tells me that while I was in our room pumping, he allowed my father-in-law to change our son's diaper. Is it weird that I was not okay with this?

I don't know if it's my motherly instinct or if I am just being weird or over protective, but I don't like the idea of anyone besides my husband and I changing out baby boy's diaper.

What do you guys think???
