I've been trying to produce an offspring with a couple since they were 37 and 39. I've tried about 8 times already and now they're almost at that cut off point where they REALLY won't be able to (48 and 50) doesn't that seem rather odd?..

I've tried the baby booster once and not more because the description says that too much may cause an opposite effect... how much is too much? What should I have done that I didn't do? It seems rather hard with this couple for some reason and I'm going to lose everything! (the house is fully upgraded) help!

I'd try the baby boost again. The description of it was worded incorrectly, there's a thread here on that somewhere, but try givin' one to him and one to her, if you can afford it. That's all I can really tell you, it worked for me.

yeah i read that post too... so basically it's the description in the manual that's accurate, not in-game... I won't spare this time!

There's supposed to be an in-game feature that stops this from happening. Usually you get a prompt to adopt a child in order to carry on the family line. Hopefully you get that!
