Time DRAGGING when nannying

I’m a 26 year old nanny and I work for a sweet family, two parents in their early 30s that work from home and I watch the 8 month old boy. I know I have no right to complain, nannying is a relatively easy job compared to post others, I get paid well and I don’t hate my day to day, but I feel so drained after the day is over, and I feel like time just DRAGS on and on. I’m with them 8-9 hours a day, I take him for walks, but does anyone have advice to pass time quicker when we’re at the house playing with toys? It just feels like the day goes on forever. The parents working from home is also annoying sometimes and it would be so much easier if they were out of the house. They don’t do anything wrong and I like them as people for the most part, but does anyone else relate to this feeling?
