Having more than one child

My classmate is interested to have five children because this is what they wanted. She and her hubby has plan for this and both of them are in their 20's. This is good for them as they are young and willing to take this opportunity.

This afternoon she sms saying that she and her hubby are planning to get married. They are not legally married but their parents have no objection of them having kids before married.

My friend is thinking of whether to have a wedding ceremony or a just have their wedding announcement on the newspaper.
