After you have been married for a season or so, your wife (or yourself if you're playing the Girl version) may wake up one morning feeling ill. The two of you will head to Hardy's clinic and you will discovers that you're about to become parents!If you don't see this family event a season after marriage, make sure that you have kept your spouse's Love Points above 60,000 for 30 days.
So keep that lovely Phantom at max LP or close to it for a full 30 days [yes, talk to him, or he'll want a divorce or something, am I right?] and all the sudden you'll run to Hardy and he'll tell you the obvious.
...Same as Mineral Town, kinda. But the kids are cuter this time around, ne?
As for how to get a girl or boy on command...
I have no clue. I really only know what's on UnT and what I've played myself, and I'm not even done with Spring Year 1 yet. I only got the game yesterday...
I hope SOMETHING I said was helpful.
