You can add children to the groups that you have already created.
See here our guide on how to create groups.
1. From the "Children" menu, select the list and "New Child".
2. Fill in the information one child at a time and save.
Note: You will be able to invite guardians while you add children or later.
See here how to do it later.
3. Once you have filled in and saved the information, you will come to the child's profile. Go back to the child list and add the remaining children in the same way.
Once you've added all the children, invite the guardians if you didn't do it at the same time. See here how to do it.
