Our kids' activities are piano lessons (once a week), church group (one weeknight, and then sunday mornings) and the a sport - right now it's baseball. THe sport is seasonal and paid in one lump sum - for the three older guys this year it was $140, and that's for 3 months. Piano is $65/wk for three kids' lessons. Other than those, we find FREE activities, LOL! We get a membership to the Boonshoft museum from Dh grandparents every year, and it's reciprocal to all our local museums (art, natural science, franklin institute and the zoo) so we do those frequently (for free). Otherwise, we do lots of local parks and playgrounds. In summer, our activity is the neighborhood pool, and for the family membership that covers all 6 of us, it's $650 this year
: We literally live at the pool from 12-6 every single day, so it's worth it for us - and saves money on the electric bill since we keep the a/c set much higher when we're not at home.
Gas for me is about $10-15 a week, I don't do a ton of driving and what I do is local (less than 5 miles from home - to grocery store, etc) We try to walk a lot, but when you're grocery shopping for a family of 6 for hte week, you can't exactly cart that home on a walk, LOL!
Groceries we've just reduced our budget to $650/month, this includes toiletries, cleaning, etc. In the summer that will go down as we garden and get a lot of produce from our garden.
Dh and I each have $50 "blow" money per month.
