Now that said, seriously, whatever floats you and/or your kid’s boat. Most days, my son’s cuffs are all the way stretched out and he specifically says “Don’t roll them Mommy!” (Which is why most of these pictures aren’t modeled!)
And on most of the remaining days, I quickly fold them up once, as far as I need to for them to stay above his feet (which is less and less every single day!). Usually I can finish this before he starts squirming because he feels ticklish. Or, if I’ve already had my coffee and actually think before I dress him, I fold them this way BEFORE putting them on him, and they stay in place.
But on a couple of rare occasions, he has been very patient, and somehow not felt tickled, and let me roll them the fancy trim way! Now unfortunately, the fancy trim way can’t be done in advance – their hands or feet will push out all your hard work.
To fold the fancy trim way (and while it’s not specifically mentioned in the pattern, I’m pretty sure that’s the technical term for this fold…), first fold the cuff inside, so that the edge of the cuff is touching their skin, and is at least as far as the cuff seam. Then, roll up the cuff once (the standard way) on the outside, making sure that you don’t roll it up too far. (I’ve wracked my brain for how to describe it, but if you hit it, you’ll know!) Voilà! A trim, fancy cuff! (For argument’s sake, on the left as “normal roll” is what happens when you roll it up once to the seam where the cuffs meet the pants, then up again, which is what is a “normal” roll in my head, whatever that means.)
This is great for cuffs around the wrists or ankles, for any grow with me patterns that feature cuffs. (Truth be told, for me personally, the fancy trim way is reserved just for pictures, because my kid is on the ticklish side of things and likes to do things himself, which I encourage. But I think it looks fantastic.)
For the waistband, on grow with me pants they’re often longer to accommodate kids at the upper limit of sizing. So far I always fold my son’s waistband down, even when he’s at the upper sizing, but every kid is different. So if you like leaving it up, or if your kid is super styling and likes to dress themself and pull the waistband all the way up, go for it! Whatever floats your boat and creates the least amount of stress.
And on grow with me shirts, I find the waistband usually tucks itself under the shirt just from putting it on. It can sit hidden up there, or be pulled down, whichever you prefer.
Bottom line, whatever gets the job done! But it doesn’t hurt to have something fancy up your sleeve! (BAHA! I just actually laughed out loud. Yep, I’m pretty much the coolest.)
