Re: should your baby carrier match the gender of the baby?
I think it should match the mama but to me that means a more mature pattern ie not care bears or such, unless the mama likes that, of course. If it's a children's print, it should be gn or gender specific.
I like to find one that matches the mama's personality. Mine is jungle print with lizards. (I have a boy). Very bright but I sell them locally and want people to ask me about my sling.
I wouldn't wear a pink sling with my boy. Maybe purple or yellow. Depends on the print.
