Mommy only!!!

My LO is 8 weeks old and only wants her mommy. My mom sister and husband will try to hold her but she'll get fussy and only be calmed in my arms. I mean...I'm flattered...but I also would like her to like other people!! I know she might just be going through a leap per the wonder weeks but I want to make sure it's a habit that doesn't stick and she'll be well socialized. Any advice? Anyone else go through this?
