Yes, only one parent can register – it must be the person in whose name the Cumulus account is held. But don’t worry: at Famigros, the whole Cumulus household is always included. This means that all adults registered in the same Cumulus household will automatically become Famigros members once the account holder has signed up – regardless of the make-up of your family. However, only the Cumulus account holder can manage their Famigros profile, enter their children’s details and cancel their membership.
