If you are considering adding a second child to your Google family, there are a few things you need to know. First, make sure that you have enough space on your account. If you have more than one child under the age of 18 living in one household, each child will need their own account. Second, be sure to add the correct information to Family Link. This will help ensure that your children can easily find each other and communicate with each other. Third, be sure to add their birthdates and parents’ names so that they can easily find them when they want to chat or play together. Finally, make sure that all of your children’s devices are connected to the same account so that they can easily communicate with each other across devices.
