Your child is a character in Harvest Moon 3DS: A New Beginning, who may appear after your character getting married. The child will look same no matter who you marry, instead of inherited your spouse looks.
In official art it depicts two children. Unfortunately, the player can only have one child.
After two seasons of birth, in the morning when you wake up the baby will be crawling on the floor. It is just the event though, as the baby will appear back in the bed and remain there after the cut-scene is over. You can now talk to it, but you can't give it any gifts.
After another 62 days have passed, the bed-baby will develop into a child (1 year since birth). At this point you can begin to give it gifts. The girl and boy like the same gifts. The child will appear at festivals (such as the Fall 31 Pumpkin Festival) and you can see a random event when the child has at least 20,000 FP.
Unlike other Harvest Moon games, Your Child can grow into a teenager rather than staying at a child age forever.
After your baby has been at the child level for at least 30 days and it has 60,000 FP or more, the Harvest Goddess will visit your house to give your child a piece of Candy. This special treat will transform your child into a teenager for 30 days (not a full 31-day season). There is another random event that you can trigger when Your Child is a teenager, but it requires you to have seen the random event from when it was a child.
When the teenage Candy wears off, the little one will return to its cute child stage. If you want another piece of Candy, give Alice the Harvest Sprite some Royal Jelly. You can get Royal Jelly from your honey bees. If you seed a bee hive with a Mountain Honey Bee from the Ancient Ruins, then you will get the honey you need for more Candy.
Even as a teenager, the child will not help players with any farm chores. Just like with your spouse though, the player can ask them to forage for wild items on Fridays or Saturdays, but only if they have 30,000 FP or more and the weather is sunny. Once the teen converts back to a child, they will not help with foraging unless you feed them Candy to return them to teen-dom. That is the end of Your Child's stage.
