Will she love her more?

My LO is 3 1/2 months old and I really want to lose the extra pounds I still havent gained. My So pretty much let himself go when I was pregnant and gained as much weight as me! We want to join a gym and go every night or so. BUT, I have a hard time leaving my LO with anyone, not that I dont trust them, but because I want her to go to me for everything. My neice always wants her grandma rather than her mom (they alll live together) because she was watched so much by her grandma. We live with my SO's parents, and I dont want my LO to go to her nana for everything and not me. Am I completely crazy? Will she start to be more dependend on her?

I highly doubt it. My mom has watched my LO since she was 3 months old (she will be 1 next week) while I work from 9-4 and my DD's always prefers mommy over everyone  

It's ok to feel that way.. I leave my son with his grandma... When she walks in he gets excited but still prefers me over her.. When he started walking he walked to her first.. That kinda bothered me but he still is his momma's little boy..

If she was with her all the time, yeah, she probably would. But you just want to go to the gym! Relax, momma.
