I spend 5 months off work every Spring/Summer. Then, the household becomes my job. What works for me is keeping the toddler in care and keeping a schedule. Each chore is scheduled in a 4-hr chunk, and can be moved around things like doctor's appointments, etc. From last year: Monday, shopping & cooking; Tuesday, cleaning; Wednesday, free day, kept my toddler in the morning so we could attend a class and then I went to Pilates after I dropped her off at care; Thursday, laundry; Friday, free day with Pilates and social engagements that could be had during the day. Friday night and weekends were relaxed, family time.
I also did all the drop-offs and pick-ups of my toddler from care during that time. So, for instance, Monday, which was the busiest, was out the door 8a-ish, drop her off at 8:30, grocery shop at 9:00, cook 10a-1p, lunch, gym, shower, 3-5p free time, 5p pop dinner from freezer to oven, pick up toddler, 6p family dinner, 7p start toddler bedtime routine, 8p toddler in bed, 8-10ish time with the husband or doing our own thing. (We're up at 5:30a because of aforementioned toddler.)
