gunna loose my mind!

I am having a lot of trouble with our guest list.. and im just about ready to cry and/or elope!

Heres my problem... Origionally we said we would invite kids becuase all my guests are OOT and i want them to be able to attend. origionally an easy solution.

but, that turned into a problem when i started to realize that the age of kids became a problem. For example, my parents friends have 2 kids who are adults, older than me, 1 is married. Do we invite them or not?

Or, we are inviting a family friend who has 3 kids and I only know 1 of them, obviously i cant invite just 1 so i would rather invite none... but if i dont invite thier kids I cant invite the kids of family friends I do know and am close with right??

So... we thought that We would invite family kids and not friends no matter the age. But then my mom wants to invite the kids of a family that is 'like' family becuase we are close with all of them.... but they arent really family. My sisters and I were IN all thier weddings and now they have kids... but i feel bad making an exception?

uhhh sorry so long, I need some help from someone who can be objective. I want to invite kids so its not an option to just say no kids.

any other ideas?
thank you!

maybe just invite the younger ones that u know the parents cant get a sitter for..i mean the kids of your parenst that r adults if u r not close to them i dont see why u have to invite those.as for the one with 3,i agree i dont think u can invite one w/o the other 2 they might get offended..i def think u should invite the ones that u r like family with..i mean just because its not blood dosent mean they r not close with u even closer than some who r blood..i hope this helps
