Obviously it will depend on the age of the child/children. With a steady increase in work done as they get older and into childcare. My DD is 4 and in playgroup/ preschool 9-3 4 days a week. I work 1 shift a week so this is what I do in 4 days I'm off and DH is working...
Take and pick-up DD from school, and afterschool activities/playdates a couplke of times a week.
Walk or run dog each day
All cleaning - day to day stuff and longer term stuff. I follow a modified version of The Organised Mum Method (Her second book The Organised Time Technique is also worth a read). One load of laundry a day (Except Saturday and Monday, our weekend).
Meal planning, shopping (home delivery) and cooking (which I get done before DH finishes work).
Personal & work admin (timesheet/expenses etc), all DDs health & school admin, my share of the household admin (some things have ended up in my name, somethings in DH from when we bought the house pre-DD). Running any Errands. Admin for my BTL house.
CPD (studying which is a obligation of my professional role).
Gardening or DIY - gardening is my main hobby but I also do all the general upkeep, in the winter I try to do a bit of DIY during the week, mostly decorating as it would not make anyones life easier if I started using powertools (this is not where my talents lie!!) - this has only been since DD has been in school all day. I also garden in the evening in the summer because I love it.
On DDs day off I take her swimming (there are 300 kids on the waiting list for lessons in our area so I'm trying to teach her myself via youtube videos), and any SALT appointments she has are always scheduled on her day off school.
On Sunday when I work and DH is off work with DD, he does everything for DD, their meals, cleans the bathroom, one load of laundry, and looks after the dog.
This way in the evening we only need to do the dishes, get DD to bed, DH does the dishes, and I get DD to bed as she won't go to sleep for him if I'm in the house. At the weekend we keep the meals simple and don't do any house work, just have fun or relax.
