People use "consignment" and "thrift store" like they mean the same thing. They don't, and the difference actually matters — especially when you're a busy parent trying to shop efficiently for a growing family.

Let's break it down in plain terms.

The real cost of kids outgrowing clothes isn't just the price tags on the individual items — it's the frequency. Children, especially in their first several years, cycle through sizes at a pace that feels almost aggressive. Newborn, 3-month, 6-month, 9-month, 12-month, 18-month — just in the first year and a half. And by the time you get into toddler and kids sizing, you've still got seasonal resets to contend with: new coats every year or two, swimsuits that don't fit by next summer, snow boots outgrown before the season ends.

One of the first pieces of advice new parents get from other parents is this: don't buy everything new.

And it's good advice. Great advice, actually. But it's also a little vague, isn't it? Because the follow-up question is always, "Okay, but what should I buy used?" Not every secondhand purchase makes equal sense, and if you're new to this, it can feel like a guessing game.
