Joint account?

My fiancé & I have been together for 2 years, I'm due in 4 months  & we're getting married next month.  I felt like he spends alot of money on  unnecessary "toys" it might not be a problem now, but with the baby coming & our marriage life starting, I really think that he should slow down on some things. I explained my point to him and he agreed on getting a joint account in which we will be saving some money on the side. Some of my friends say it's too soon, some of his friends think that im using this opportunity to take advantage of him. Do you guys think I should go on, or wait?
