When to get married?

So my fiancé and I recently got engaged, and the same week found out we’re expecting! He’s 28 and I’m 26, and we currently live in a 6th floor 2 bedroom apartment. My parents gave us the option to do the big wedding, or do something small and they would give us money for a down payment to buy a house. We decided we want to take the money to buy a house since it just seems like it would be pretty difficult to raise a baby in our small apartment. However my parents want us to get married before the baby comes, even though we’ve said that we would rather wait. So I guess I’m just asking, what are everybody’s thoughts, suggestions, or advice on whether to get married before or after the baby comes?
