Hafan y Sêr centre 'a break' for families and carers
Ben, Rhodri, Jack and Portia say they feel "lucky" - all four have a bed for the next few nights in a new respite centre.
They all need specialised care, and the centre is a chance for their parents and carers to take a break.
But the Hafan y Sêr centre in Gwynedd is already oversubscribed - with a waiting list for new places.
It has added urgency to a campaign recruiting volunteers for new foster respite care roles in the region.
Ben Hibbard, 17, showed BBC Wales around his home for the next few days.
