Where's your petty cash mama? Some things that get me off budget (that you may or may not do) are : gifts b-day parties ect, school field trips and school pictures, and fund raisers, books and magazines for mom and dad, OTC medicines/supplements, out of town trips/vacations, vet bills and flea control, hair cuts, and my color 3x's per year, house maintenance, and or repairs, postage, thats all I can think of right now.
I thought of a few more
YMCA, charity donations, lessons (which I budget for but then they have outfits shoes ect.., summer camp/activities, medical bills, scouts, car and house taxes, car tag renewal, the IRS, continuing education (if your dh needs that), and babysitters.
I should print this we are doing our budget in Jan., No wonder I can't make one work if I forget all this stuff!!
