Clarify who is Invited

Be very clear from the get-go of your wedding planning regarding if your guests are allowed to bring a guest and if you are inviting children. It's a hard decision to make, but once it's made, make sure you stick with it so there are no controversies later on. Most people will understand you have guest and budget limits that force you to cut corners in some places. And if they don't - do you really want them at your wedding anyway?
