So you want to carry on the Virtual Family name, you want to have a baby, well if you just started a marriage this be easy. Start by dragging a person to a bed, wait till' you see action " Making bed" then when he or she is done, okay this is the part that's hard, quickly drag the other person to the one who made the bed. Make sure the couple is close to the made bed, otherwise they will be tired and you will have less chances of having a baby. If you had very recent birth this may not work.
