If your child logs into Pokémon GO using Niantic Kids or Pokémon Trainer Club (PTC), you can opt into enabling social features such as Friends, Gifting, and Trading and Trainer Battles for your child in either the Niantic Kids Parent Portal or Pokémon Trainer Club website. You can also revoke your child’s access to these features at any time.
If you enable social features on your child’s account, your child’s friends will see your child's Trainer profile and limited information about the location where your child initially collected Pokémon or Gifts. When your child makes new friends, you will receive a digest email listing the new friendships your child has made that day.
