To have a child, the following conditions must be met:
- Get married.
- After marriage, upgrade your house to "super size". 700 wooden lumber and 50,000 gold are required. Additionally, you can pay 80,000 G if you don't have the lumber.
- After upgrading your house, buy the baby bed. This costs 10,000 G.
90 days after your wedding date, your child will be born. The gender of your child is chosen when they're born, so be sure to save before the due date of your child's birth. If you don't like the gender of your child, reload the game and you may have a chance at the gender that you'd prefer.
Once your child is born, they will remain in their crib for two years. Your child will not accept gifts and cannot be picked up, but you can talk to them which will count as 200FP. Your child will have a birthday each year which can be celebrated at 6PM, but even so, he/she will not grow until two years have passed.
Two years after your child is born, they will be crawling in the morning when you wake up. Your child will now crawl around the inside of your house all day. You also gain the ability to give gifts to your child to increase his or her heart level. Each gender prefers different gifts. It will remain in this stage for 2 more years.
After two more years, your child will hit their final growth stage. Your child can now walk around the house! Although the child stays in the house all day, he/she can also be found walking around at festivals. Your child will still accept gifts at this point as well.
