First time boy mom

I saw a post about being a first time girl mom and I realized me and my fiancé are going through the opposite. Combined we have 4 girls and this is our first baby together and it’s a boy. Is there anything we should know?? This is going to sound so dumb but I have no idea how to change a boys diaper. We both feel like first time parents all over again lol but it’s exciting having a new experience together especially since it’s our first baby together. I assume most stuff doesn’t change but if there’s anything that you felt was different or stood out with having a boy please let me know!
