Every week? Nope. Every two weeks and stretch it out if possible. Anyway, since my kids were responsible for doing their own laundry since they were about 12, that's how it went. Being tied to the washer every weekend without fail isn't all that practical in my opinion.
And yeah, you could look at it as great value that we stretched it out for the two years. But really, for the last several months, they were not really that wearable but we just made do, stains, holes, rips & all. It wasn't as if the clothes really lasted that long, we just made them last in lieu of buying new ones.
