I'm interested in what other SAHP responsibilities are and how you've reached that balance.
I'm a SAHP and have two small children. 18 months and almost three.
DH has a busy and stressful job. Works long hours. Early starts, late finishes etc. Hasn't been helped by Covid as he's now inside constantly and like most people isn't really enjoying it.
I'm responsible for the house and children.
We share bath time and bed time responsibilities.
DH will cook breakfast, lunch and dinner one day on the weekend but other than that it's my area.
I do 99% of shopping and nursery drop offs. All laundry and any house admin things are solely my area.
We share the nightly tidy up and alternative who does what each night.
We also have a cleaner who comes once a fortnight to do the bathroom etc.
So I wonder what others are doing?
I must admit to getting annoyed when I arrive home from the nursery run to find breakfast things still on the table but is that my responsibility to put them away, as that's my "role" in our house. Or should I speak up and say something?
It often crosses my mind 
I suppose I'm used to juggling the children and getting stuff done, whereas DH is a one thing at a time type.
Interested to hear what others do!
