God some of the comments on here are a bit mean, sorry. Maybe I'm just inefficient but I reckon I could easily lose the 6 hours a child goes to school for. Cleaning, gardening, exercise, lunch for me, washing up from breakfast and lunch, make dinner, maybe do some batch cooking for the weekend or other dinners, do a bit of searching on FB for second hand toys etc, supermarket shop.... It'd easily go!
Not to mention, if you stay at home you'll no doubt be expected to do everything mornings, evenings and weekends because you're "off all day" - so if that's the case then you really should be taking a nice coffee break and a longer break a couple of times a week.
It sounds lovely if you have a nice partner and you use your time well - it must mean your weekends are much more free for everyone to have fun as a family, but I don't know why people think "what do you do all day"!
I am back to work now after maternity leave and honestly it's such a break after 14 months at home. If I stayed at home until school years, I think I'd do it on the proviso I get an equal number of years off work with them in school to make up for it!
I also don't know who these people are who keep saying they work full time and see their child the same as you. My husband's hours mean he is out of the house for 10+ hours a day, and mine are at least 8-9. Kids are in school for 6 hours usually so you're doing 2 to 5 hours more childcare per day than a full time worker, or else they are not actually full time.
I hate how many people on Mumsnet seem to think childcare and housework aren't much effort and you should be doing all of it unless you work 50 hour weeks. I can only assume they have potato babies that just sit there because mine is a whirlwind of chaos!
If it helps, nobody I know would ever express an opinion either way on what parents do. It's none of anyones business! It's a noisy minority that have these strong opinions one way or another I think.
