I don't actually fund all of those categories fully at the moment, since I'm trying to get everything paid off except the house in the next few months. I do fund most, but I think Vacation, for instance, is optional.
I'd only put money in a category if we needed it. Kids get haircuts rarely, as do I, and I shave DH's head. So we're looking at maybe every 4-6 months, we might see a number there. Same for clothing, etc. Gifts as needed.
Some annual bills are small enough that I probably don't really need a sinking fund for them, but it's so cool to feel all prepared.
And I'll be adding a few more in the next few months: 529 payments for the 2 kids who don't have college funds (weird grandma was super generous with just one kid), IRA for me. College expenses for mama.
