Slightly different, in that my eldest was diagnosed ASD at 3, and my autoimmune disease started to flare for longer periods, so for the forseeable future I'm a SAHM.
My eldest is now at school, but is home off the school bus by 3. My youngest is two, so aside from a bit of preschool, he's home with me, so we visit friends a great deal (chockablock with SAHP around here), the library, gymnastics classes, playground etc.
I'm never home between the hours of 9-2, and am lucky in that we can afford a cleaner, and have a meal delivery service for my husband and I, so beyond kid cooking and an hour of cleaning in the evening, my focus is on the younger guy in the am, and afterschool activities/play dates/brothers playing in the garden in the pm.
I do want to start my own business and return to work, and realize that I'm incredibly lucky to be in this situation which allows me to honour my current needs with planning for future endeavours.
I probably would not be a SAHP if my health wasn't an issue, though I would almost certainly want to work part-time.
