Sorry if this question was already posted, I did lurk first but couldn't find it

Basically, I've asked my cousin's kids to be my FG and RBs. But then just now, I remembered my aunt has a daughter who's the same age as my FG (8). I'm trying to come up with something she can do so my aunt won't be offended that I included my cousin's kids but not hers. (There's way too much family drama as is, so I'd rather not contribute to it!) My mom suggested maybe having her hand out the birdseed or something so she doesn't feel left out. I don't want her to be a FG too because she's really spoiled and obnoxious lol. Ideas?
