A Parent’s Dream Water Bottle!

I got the Simple Modern Kids Water Bottle in the "Under Construction" design for my 5-year-old, and it’s been perfect for school and weekend adventures. The insulated stainless steel keeps his water cold for hours—no more lukewarm sips by lunchtime! The straw lid is super easy for him to drink from, and I love that it hasn’t leaked once, even when tossed sideways in his backpack.The 14oz size is just right for his little hands, and the fun construction-themed print makes him excited to hydrate. After weeks of use (and plenty of drops), it still looks brand new. Cleaning is a breeze too—the straw comes apart easily for a thorough wash.If you need a durable, leakproof bottle that kids actually want to use, this one’s a winner!

Super cute and recommended

Cutest cup ever! Specially for your paw patrol lovers easy to open and close straw keeps his drink, nice and cold. Only downfall is if straw is left open, the drink will spill very easily if not sitting straight up.

So cute!

We have finally found the ultimate water bottle for our son, and it's the Simple Modern kids' version with the dinosaur print! It is absolutely perfect for daycare, school, and trips to the park.The main reason I love it is the design. The dinos are super cute and vibrant, which actually makes my son excited to drink his water. The flip-top straw lid is brilliant—it’s easy for his little hands to open and, more importantly, it is genuinely spill-proof when closed. We’ve had zero leaks in the backpack so far.It’s durable, too. It’s been dropped on pavement countless times and just keeps going. The stainless steel keeps his drink cold all day. It’s simple to clean and fits perfectly in his lunchbox and the car seat cup holder. A parent and kid win! We will definitely be buying more designs as he grows.

Great toddler bottles - dirae, leak resistance, and easy to clean

We absolutely love this 14oz stainless steel bottle! It’s sturdy, well-designed, and perfect for toddlers. We started with one and after using it for a few months, my little one liked it so much we ordered a second one.It’s mostly leak-proof — if your toddler is actively shaking or playing with it, you might notice a few small drops, but nothing major. Even if it falls, it doesn’t spill everywhere, and any small leaks are easy to wipe up.The stainless steel body is a big plus for us — no plastic taste, no worry about microplastics, and it keeps water cool longer than plastic bottles. It’s also easy to clean and built to last. Highly recommend for everyday use, whether at home or on the go!

Our Go To

These are our go to for my toddler. Great quality and fun colors. Do great in dishwasher (we wash them almost daily/multiple times a week). We do replace the straws sometimes and sometimes do leak over time, but overall worth the money for the cute patterns and dishwashing!

Great durable, and leak free cup!!

This cup is made very well and seems like it will hold up well! My two year old daughter was so excited when she opened it up. It comes with a replacement straw. Also the spout pops out so you can clean underneath it. I definitely would buy another cup from this brand! Being lead free is absolutely a plus and a must!
