Need toddler and kid lunch boxes for back-to-school?
I confess, I am a serial lunch packer; I've tested dozens of lunch boxes over the course of YEARS. Whether you're packing lunch for a toddler, preschooler, or elementary school student, these are the lunch boxes I recommend based on durability, ease of use, leak protection, and food safety.
A few years ago, when my three girls were ages 9, 10, and 12, they looked at each other over breakfast as if they had discussed something serious without me, silently nodded together that it was time to have a chat with mom, and declared that they all needed new kid lunch boxes for the upcoming school year for their lunches and snacks.
Oldest: “Nothing that stands out. Just nice and normal.” Middle: “ Not too small. I’m always hungry at the end of the day. And it needs to keep hot foods hot and cold foods cold.” Youngest: “No unicorns or sparkles. Nothing babyish.”
Indeed, I had been packing their lunches in the same personalized, Pottery Barn, insulated lunch totes for years. They were rather indestructible despite having been machine-washed dozens of times, but my girls had outgrown the designs and were ready for something new.
Given the many eco-friendly, innovative kid lunch box designs on the market, it was definitely time for an upgrade then, and we’ve made upgrades a few more times since, as new designs and innovations continue to come out.
So each year, I dig through what's new and share what I find, because a good lunch box is a bigger deal than it sounds. Pack it well, and your kid comes home fed, focused, and in a decent mood. Otherwise, you may find yourself dealing with a hangry meltdown at 4 pm. Let’s dive in!
What to look for in a lunch box for kids and toddlers
As a pediatric dietitian, mom of three, and serial lunch packer, I find these features most helpful in a lunch box for toddlers and kids.
Easy to open: Most kids aren’t given enough time to eat in school. If the lunch box design is challenging or time-consuming for them to open, they may run out of time to eat as much as their bodies need and want.
Multiple compartments: Lunch boxes that keep foods separate from each other help make picky eaters feel more comfortable and encourage caregivers to pack a variety of foods from different food groups, which encourages little eaters to eat a variety of foods as well. This is key for helping kids get the different nutrients they need to thrive and grow. It also helps prevent blood sugar dips and spikes that can make it difficult for kids to stay energized and focused during school.
Leak-proof: Nothing is worse than a backpack full of leaked lunch!
Insulated: Food safety is key! Machine-washable insulated lunch totes with cold packs offer a great way to help keep foods in bento-style boxes at safe temperatures throughout the school day. Some lunch totes also include 2 compartments - one for cold foods packed with a cold pack and another for hot foods packed in a thermos-style container.
Which lunch box is best for toddlers and kids?
As we approach back-to-school, I thought I’d share the lunch box brands we like and have used or will be using during the school year ahead. All opinions are my own, and I have not been compensated for writing this blog post, although some of the brands below sent free product samples for me to review.
Best Bento Box for Kids: Bentgo Kids*
We've used Bentgo Kids* alongside our old Pottery Barn totes in the past while my girls were in preschool and elementary school, and they stood the test of time. I've never seen one leak, even when packed with dips and wet foods. Five compartments keep everything separated, which makes it easy to pack a real variety. It is lightweight, easy to open, and has super cute patterns.
Bentgo also makes a stackable Salad Container-style box* for mix-ins and dressing, plus a Chill Box* with a built-in removable ice pack.
Bentgo Kids is rated for ages 3–7 while the Bentgo Fresh* fits older kids and teens better. The tray is dishwasher safe. Bentgo recommends hand-washing the outer box to protect the seal, but I've been running the whole thing through the top rack for months with zero issues.
Bentgo also sells super cute, soft-shell Insulated Kids Lunch Bags* with mesh pockets for ice packs.
Best Stainless Steel Bento Box for Kids: PlanetBox Rover*
The Rover has four main compartments plus one smaller one (a nice spot for trying out a new food with a picky eater, in my opinion!) The box itself isn't leak-proof, but it comes with two leak-proof containers built for wet foods. It's durable, easy to open and clean, and dishwasher-safe.
PlanetBox also sells a sleek insulated tote,* and the magnets on the Rover are a nice touch for personalizing. Everything is free of lead, PVC, phthalates, and BPA. Best for ages 3+ with smaller-to-moderate appetites.
Best Lunchboxes for Toddlers:
If your toddler is still more snack-grazer than lunch-eater, the Monbento Snack Box* is a great starting point. Compact and adorable, the Monbento Snack Box is made in France from BPA-free polypropylene, a sturdy, recyclable plastic, and it's leakproof thanks to a silicone seal around the lid, which matters the moment you pack anything even a little wet. It's compact enough to disappear into a smaller backpack without getting crushed at the bottom. The flip-top cap is genuinely easy for small hands to manage on their own, and the whole thing is dishwasher-safe.
For the youngest lunch-packers, the Munchkin Lunch Bento Box* is the one I'd reach for first. It's rated for 18 months and up, which makes it a great option for those kiddos who aren't quite preschool age yet.
Five compartments keep foods separated, and it comes with its own stainless steel utensils that snap right into the lid, so nothing gets lost in the diaper bag. It held up impressively well in independent leak-resistance testing, though I'd still skip really watery foods. Everything, utensils included, is dishwasher safe, and at around $20, it's an easy way to get a toddler started on solid lunches without a big investment.
3. b.box Mini Lunch Box*
The b.box Mini Lunch Box* is a solid step up once your toddler is eating full lunches instead of just grazing. It has three compartments, and one of them has a stretchy silicone seal built to hold a whole piece of fruit, an apple or a clementine, without you cutting it up first.
There's also a removable divider, so you can resize the compartments as your kid's appetite grows instead of buying a new box every year. It comes with its own gel cooler pack, which is one less thing to remember on your way out the door.
Best Bento Box with Built-In Insulated Container for Hot or Cold Foods: OmieBox*
If your kid wants a warm lunch (soup, leftovers, mac and cheese), OmieBox* is built for exactly that. The vacuum-insulated thermos pod sits right inside the bento compartments, so warm pasta stays warm right next to cold fruit, without one temperature ruining the other. The latch system is simple enough that most three-year-olds can manage it on their own, which makes it a strong pick for daycare or preschool, not just older kids packing their own lunch.
For older elementary and middle schoolers who've outgrown the original, Omie now makes OmieBox UP*. It has a bigger, 12-ounce thermos (40% larger than the original), a removable ice pack, and enough room underneath the thermos for a full sandwich. It's a good next step once a kid decides the original box feels “little kid.”
**TOP TIP** If you'd rather use a standalone thermos than a full bento system, the ZOKU Neat Stack Food Jar* and Hydro Flask Food Jar* are worth a look, too.
Best Bento Boxes for Sandwiches:
1. Bentgo Pop*
My middle daughter, the one who's always hungry by the end of the day, has claimed the Bentgo Pop* as her favorite. It's built for bigger kids and teens, and it actually holds a full sandwich in the main compartment instead of the half-sandwich squeeze job some boxes force on you, plus two side sections for fruit or chips. There's an optional divider if she wants a fourth compartment instead. The lid clips down tight and hasn't leaked on us yet, and the tray pops out for the dishwasher or the microwave.
If you'd rather skip plastic altogether, the LunchBots Large Cinco* does the same job in stainless steel. It's five compartments, sized specifically to fit a full sandwich plus sides, so you're not stuck cutting sandwiches into triangles to make them fit. It isn't leakproof, so this one's for dry foods only, but it's dishwasher safe, and it's held up well over years of use in our house.
**TOP TIP**: If PB&J is in regular rotation, a sandwich cutter and sealer* crimps the edges shut so nothing leaks out and the bread doesn't get soggy by lunchtime. It's basically a homemade Uncrustable, and it's saved me more mornings than I'd like to admit.
Best Non-Plastic, Leakproof Option: Yumbox Prêt*
If you want to steer clear of plastic but also get the leakproof benefits, the Yumbox Prêt* is stainless steel with a silicone lid, and it's genuinely leakproof, not just leak-resistant. At just 1.1 lbs, it's light enough for a kid to carry, and the latch is easy enough that most 5- to 8-year-olds can manage it on their own. The one tradeoff: it's not dishwasher-safe, so handwashing is best to maintain the seal's longevity.
Most Affordable Bento Option: Bentgo Easyboxes*
If you are looking for a great, durable budget option, the Bentgo Easyboxes* (formerly EasyLunchboxes) are the pick. The set comes with four trays and four snap-on lids, and each compartment holds about half a cup, so they're an easy way to portion snacks, dips, or small lunches without buying a pile of mismatched containers.
They're dishwasher-, microwave-, and freezer-safe, made from BPA-free plastic, and stack neatly in a cabinet when you're not using them. At under $15 for the set, they won't outlast a stainless steel box, and a few parents have mentioned the lids can pop up if you overfill them, but for the price, they're hard to beat as a starter set or a backup for the days your sturdier lunch box is in the wash.

Best Lunch Boxes and Accessories Worth Adding to Your Cart
Beyond the lunch box itself, a handful of small extras make the biggest difference day to day. Here's what actually earns a spot in our rotation:
If lunch gets smashed in your kid's backpack, or you've got a kid who just tosses their bag around, this hard-shell Hydro Flask lunchbox* solves it. It zips tight and holds temperature well, keeping cold foods cold and hot foods hot.
A couple of reusable ice packs* that actually fit your lunch box's insulated pocket. It sounds minor, but the right-sized ice pack is often the difference between food that's still cold at noon and food that isn't.
Another great option is a PackIt freezable lunch box* with built-in ice packs. Packit also sells snack boxes with freezable walls as well, that are incredibly convenient for after-school activities.
A set of kid-sized reusable utensils* that snaps into its own hard case is worth adding to the rotation, too, so a fork doesn't end up loose in the bottom of the backpack by Wednesday. Skip the ones that only come in a soft fabric pouch; the hard case is what actually survives a backpack.
For sandwiches or snacks on the side, I use Stasher silicone bags* instead of Ziplocs. They're dishwasher-, microwave-, freezer-, and oven-safe, so they hold up to way more than a single lunch cycle, and they seal well enough to handle cut fruit or something saucy without leaking.
Final Thoughts…
The best lunch box for your child depends on their age, appetite, and the types of food they enjoy. Whether you're packing lunch for a toddler heading to daycare or an elementary school student who loves hot leftovers, choosing a durable, leakproof lunch box can make school lunches easier for both you and your child.
