Swiss Travel Pass & children's co-travel card

Hi I am looking for some information I am a little confused. So I will be traveling with my 15 year old niece and I will be purchasing the STP for myself and was suggested the Children's CO-Travel card for my niece. However, does that mean we have to purchase tickets for every ride at half price for her ? Many thanks.

No, once you have paid CHF 30 for the Children’s Co-travelcard, that is her ticket for all your travel.

There are more details here:
