It's Kids' Stuff!
Continued (page 2 of 2)
If it turns out that you do have to nix some kids, be consistent.
You can draw the line however you choose (one safe rule: immediate family and first cousins only). No matter which guidelines you set, it helps to personally call those parents whose children won't be invited, and to do it as soon as you can. Your honesty should be well-received, as long as you're fair and you give enough advance notice.
