@adaline I guess I see a lot of these things as just normal life tasks - I just get on and do them and I don't really understand how they seem to take up hours of people's time!
Normal life tasks = life admin. Just semantics.
When it's just you, it doesn't take hours.
When it's you + DC x multiples thereof, it does. Disproportionately.
Perhaps it shouldn't, but you'll just have to trust us ... it does.
And you also have disproportionately less time to do any of it in.
Food - the planning, shopping, cooking and clearing up from becomes A Thing.
Booking appointments - you have no time, if you do have time to make the appointment you need to consider how it is scheduled with relation to childcare etc.
Laundry - it's no longer a 15 minute task, no matter if you have a tumble dryer and ditch the ironing.
Childcare/preschool/school admin - out of control, no way out of this.
House maintenance - didn't own anywhere that needed it pre-children. Now we do. Arses.
and on and on.
I think your life is as busy or slow as you make it, for the most part.
Which is fine, when it's you. As soon as it's you plus DC, not only do they make your life busier against your will just by existing, but you also are choosing on their behalf about their lives. And wanting the best for them is a balance between how much you personally can take on without losing the plot and how much they desire/would benefit from.
My life is FULL of admin in a way it never was pre-kids!
