I’ve been in a similar position, including a dd with special needs.
I think you need to divide life into 4;
1 Work
- Children/ Family
- House/garden
- Dog
In each category think about what you like doing and don’t like doing, also of the don’t like doing there are things that your family like or need you to do. This process should leave you with a list of what you like or need to do and tasks that you want someone/or thing to do.
Then look at how you can get these things done, so
- Work, extra help from a virtual assistant, but also is there anything that you could purchase that would make you more efficient eg upgrade of laptop, using Apple cloud etc. Try to think a bit outside the box, eg I switched to a Nespresso at work as it was so much quicker
- Children
It may help if housekeeper is in charge of Laundry and washing sports bags etc. I only got rid of the stuff that my dc would not notice.
- Home/ garden
Home, as others have said get a good housekeeper, a few days a week, give them a list of jobs that must be done and a monthly task list. Think about if you would prefer this when you are in the house or out of the house.
Also think about gadgets that could help, we have 2 dishwashers, so you could load but not have to unload as housekeeper could you do that, similarly we have a Roomba robot vacuum cleaner, tumble drier etc. We also have an extra freezer and I do a regular order with a organic farmer for our beef etc
Use someone like Ocado for groceries and have a weekly slot on the same day. You can set up a basic weekly list and also biweekly or monthly additions.
Maybe get the housekeeper to put this away or have it delivered at the weekend.
Think about a weekly menu, maybe a cook meal one night, or something like Hello Fresh to help. If you use milk get a milk man/woman.
Garden, get a proper gardener , make sure they do the whole job, ie tidy, fill green bin or dispose and clean patio and cut lawn. Also could you get a robot mower , would only work with a smallish garden.
- Dog
I would find a lovely professional dog Walker, don’t expect your housekeeper to do this. Ask how much exercise they will get and check that they actually like dogs.
I would start with the 2 days that you work in the office.
Personally I love walking my dog but have a dog Walker 1 day a week, dog goes for half a day, mid week and loves it, they will do more if needed. They also board him when we go away. Ask others who they use and if they would recommend.
Hope that helps
