Next EP might be Sims 4 Generations

Children can also help with gardening, also from the patch. But I believe the patch was added to base game so all can enjoy these activities and wouldn't exist if not made for use in Cottage Living. Children, and even toddlers, can interact with the farm and wild animals. I believe living on a farm and managing it is very much a family activity as all members are needed to make a farm successful.
