@outlander , respite care doesn't have to be termed 'respite'. It's respite for you. Could you engage your pop in social events with a support worker to take him out shopping or a coffee?
Im not sure how able he is, but in my local council , they set up events for the elderly such as walking, walking football, coffee catch-ups, dance, games, movie nights, day trips, art classes, exercise, yoga. All these events are low or no cost.
I also know people who go to the house just to have a chat to the person, watch a movie together, have coffee together. This type of connection is probably the type of respite your pop needs (in his own home) rather than sending him away to a facility.
What are your thoughts?
