How To Word Your Wedding Invitation For A Child Under The Age Of 18

How do I word my invitation for a child under age 18?

For a child who is under the age of 18 you would word your invitation accordingly. On the outer envelope, nothing would be listed in regards to the child. On the first line of the inner envelope it would read Mr. and Mrs. last name. On the second line the child's name would appear. If there's more than one child their names would appear in birth order.
