Grandparent - baby interaction

I’d like to compare how my babies grandparents compare to others to establish what’s ‘normal’. When my lo was born 3 months ago I couldn’t rest if someone had taken her out of the room or if someone was holding her for too long (more than 2hrs). Now that my hormones aren’t as raging I’m used to this feeling and started to accept that it’s normal and I love to see family loving on her. Having said that I’ve reached an equilibrium with my family, where I often feel like we’re sharing the time with her, however with my in-laws my mil specifically she hogs her, disregards me and I can go up to 6hrs without being close to my baby and it breaks my heart a little because I feel like they’re taking my baby away. At the same time if I say anything I’ll sound crazy and irrational.... maybe I am!
