The rules vary by family, but we did not invite children to our wedding. People may complain, but if they just find a sitter, they actually have more fun. You're giving them a night out, dinner, dancing, etc. They can find a sitter.
As far as +1 or +guest goes, you don't have to do it. Basically, if you have to write +1 on the invitation instead of the name of the person they'd bring, you're not obligated to add it. The single folks will have a fine time hanging out together, since I'd guess most of them are your buddies anyway.
