Mine still comes home and we have convos on the way home in the car etc, just an hour and a bit later. He's an only child, so probably a bit different as he gets a lot out of OSHC as he has his little friends there to play with and watch movies (tough life, isn't it?)
I'm planning, hopefully in the next month, to work hours 9-3 at home. Eliminating OSHC costs, vacation care costs etc whilst still earning at least some income.
I think for a lot being a SAHM while kids are in school would be very beneficial. My personality though.. I would go stir crazy. So it depends on what level of adult company you need, what kinds of stimulation you need. I'd sit down with a pen and paper and work out the pros and cons
