I HE my ds1 and fully intend to (and indeed am) HE my ds2.
My dh works full time. I have not worked outside the home since having my ds1 7/8 years ago.
We manage.
My car is 5 years old and I will basically have to drive it til the wheels fall off! We dont go on expensive hols like we did pre dc. We dont drink (much) we dont smoke, we all have bikes so we can take off into the countryside if its a nice day.
Ds1 does karate, swimming and beavers which do cost money, but he would have done them even if he had been at school anyway.
Bear in mind, if your dc dont go to school you have no uniform/PE kits to buy each year, no lunchboxes to fill only to find them coming home still full at hometime, no pleas from the school for money for trips, book clubs, after school clubs etc
I have found that I spend much more on petrol now than I used to but thats because we are so busy all the time!!! Another plus is that ds1 eats much better now too.
I would work PT if I wanted to, but at the moment we have so much going on so it may not happen til my dc are older. I would also like to continue with my PT OU degree at some point.
HEing your kids is hard work. Its also wonderful, enriching and surprising...ds1 and I have spent this morning at a "forest skills" course at a local nature reserve..... he made a den, whittled a willow stick, used it to toast marshmallows and dough balls over a fire and made a crown from leave and berries!!!
HE does not have to cost lots of money....if you take the autonomous approach the internet and libraries will give you all you need.
What always surprises me is the amount of teachers I meet who HE their kids!!!!
