Only merge children if you accidentally created duplicates in your child care.
To merge children they must both be associated with the same family. To do this, either add both children to the same family, or merge the families.
What happens when you merge children
The new child gets assigned to the following from both children
Current selected family
CAUTION: This cannot be undone
Click on the child you need to merge on the children page
Click 'Family Settings'
Select 'Merge Children'
from the drop downs, choose the 2 children that need to be merged
Click 'Confirm Merge'
You will not be able to access the children while this happens. If there are a lot of schedules or invoices that are associated with the merge, the process can take a while.
