Silly baby competitivness

I don’t know why this is bothering me so bad. My husbands cousin just had a baby last month and we’re all so excited for them. However, my in laws (and some others) keep making it feel like competition or something. I feel like they’re always being compared. And if someone says something like “Oh your baby’s outfit is so cute!” They’ll chime in with (we will call the cousin Sarah) “We got Sarah’s baby the cutest outfit” and pull out a ton of photos. Or sometimes if people are talking with us about our baby they’ll randomly jump in with “Sarah’s baby is so cute. They let us hold her a lot last weekend. She’s the cutest baby.” And it is really starting to get under my skin and I know I shouldn’t care. It’s happening with milestones, looks, clothes, etc.
