My couple are only 37&38 and they have one bio kid and the other they adopted when he showed up on their doorstep. The kids are 12 and 13. Every time I try to get the parents to have another, they argue or nothing comes of their trying. I can't do the doctor consul and booster shot thing because they don't make enough. He only makes 90 something and she makes 70 something. I will keep trying though lol. Mine are still on first generation. I only started this game a few days ago lol.
