How to Organize Baby Clothes by Size
Babies grow incredibly fast, so naturally they outgrow their clothes quickly as well. This is why I always advise moms to organize baby clothes by size right away.
The best way to organize baby clothes by size is to sort them using drawer dividers, bins and closet dividers.
The trick is how to do it in each location in the nursery and that’s what we’ll dive into next.

1. Decide which clothing to fold vs hang.

Before you tackle organizing baby clothes by size, you’ll want to decide which clothing you’ll hang and which items you’ll fold.
Here are common preferences when it comes to which baby clothes to hang and which ones to hang:
- Onesies: I prefer folding onesies, unless it comes as part of an entire outfit, in which case I hang.
- Baby Shirts: I prefer to hang nice shirts.
- Baby Pants: I like to fold baby pants, unless it comes in an outfit.
- Pajamas: I fold all pajamas.
- Dresses: Hang
- Rompers: Hang
- Seasonal or clothes that are too big: I use the same system as above. This is where organizing baby clothes by sizes comes into play.

2. Sort hanging clothes by size using closet dividers.

Once you figure out which clothes you’ll be hanging in the closet, you’ll want a way to divide them by size.
Closet dividers are the perfect way to do this.
I find it helpful to hang baby pants that correspond with an outfit on the same hanger as the top. It’s a nice way to pair outfits together.
If you’re storing items like swaddles, baby pajamas and outgrown clothes in the closet, I recommend using baskets on a shelf or the floor to continue to divide by size.
It’s also a good idea to have a specific basket for outgrown clothes. When you’re taking the clothes off baby for the last time, you can throw them in here to wash before storing away. This is incredibly sad, I know!
We’ll dig into storing outgrown baby clothes by size a bit later.
3. Organize folded baby clothes by sorting into drawer dividers.

When you’re organizing a nursery dresser, using drawer dividers is a must-do.
These dividers allow you to either roll or file fold your baby clothes, so you can see everything you have in an organized way.
Drawer dividers also allow you to organize baby clothes by size.
I like to use drawer dividers to sort onesies, pants, socks, pajamas, and all of baby’s current clothes in the first drawer. Then I sort use each remaining drawer to organize baby clothes by size.
So our first drawer is baby’s current clothing sizes. I file fold all the onesies and place them in dividers. I do the same with all the rest of baby’s clothes.
Then the second drawer is the next size up and the third drawer is the next.
Any other size that I can’t fit in the dresser I divide and store in baskets or bins in the closet or slide under the crib in a storage unit.
4. Store outgrown baby clothes in bins by size.
Babies grow quickly, which means they grow out of their clothes quickly as well. How do you store away outgrown baby clothes by size?
I recommend using bins for each size of clothing that you can store away long-term. You can label each bin by size, for example: newborn to 3 months, 3 to 6 months, 6 to 9 months, 9-12 months, and onward.
Having outgrown baby clothes organized by size in each bin is helpful for donating, giving away hand-me-downs to family or friends, and if another baby comes along!
Why even organize baby clothes by size?

It can be overwhelming when you gather all of your baby clothes and start putting them away in the nursery.
I recommend organizing baby clothes by size for a few reasons.
- You won’t miss out on putting baby in an outfit before they’ve outgrown it.
- You can easily grab the next size up when you notice baby is starting to outgrow his or her current size.
- You’ll know which sizes you’re lacking, which will help with budgeting future clothing purchases.
- It just gives a nesting mama a sense of peace.
