over protective ?

hi i’m due march 6th with my baby girl salem and

i was wondering if i would be doing “too much” if i set a age limit on who can hold her my fiancé has a little sister she’s 10 but i really don’t want nobody holding her unless they are 13 or older it just makes me nervous when little kid are holding babies and treat them like baby dolls. and i wouldn’t completely not let them have contact i would just rather his sister not hold her until she can at least sit up on her own
