    • Worth it. Such a great bottle for toddlers!
Color: Preschool Minnie Size: 12 Ounces
We got this water bottle for my toddler when she started daycare/preschool and I honestly can’t think of a single negative thing to say about it. We’ve been using it for about seven months now and it’s held up really well with standing rough and tumble usage and being lugged back-and-forth between home and school every day. I really love that. It’s so easy for them to open and close themselves because it gives them some independence over something that’s so crucial – hydration! It keeps water cool and is pretty easy to clean. I love the colors and design and the size fits into the cup holders in the car seat well and into her little hand fairly well. There are a few spots that have chipped over time, but that’s to be expected with heavy usage. I definitely recommend this bottle. ... show more

    • Perfect water bottle for kids
Color: Bluey Size: 12 Ounces

Review Image by SkyJ
This 12-ounce water bottle has been a great choice for school and outings. The size is just right for a child, and the straw makes drinking easy without having to tip the bottle back. The fun character design makes it more exciting for kids to bring along. I really like how well it keeps water cold for hours. The stainless steel construction feels sturdy enough for everyday use, while the push-button lid and carry handle are convenient for little hands. The lid also closes securely, which is helpful when it’s packed in a backpack. The removable straw makes cleaning much easier, and I appreciate that it’s BPA-free and dishwasher safe. It’s been a dependable bottle for school, trips, and playing outside, and I would definitely recommend it to other parents. ... show more

    • Durable and bright design for a toddler
Color: Stitch Size: 12 Ounces
Perfect size, easy to hold and handle, and nice bright design for my 5 year old. They can open the lid easily to use but is tight enough it doesn’t unscrew easily. For a child, it will leak through the straw if turned upside down when it is open. Doesn’t seem to do that when the lid is closed. Good quality and design. Price is in par with this type of water bottle and brand. Stays cold all day with some ice in it. ... show more

    • Favorite for kids
Color: Avengers Size: 12 Ounces
My favorite water bottles for kids. Easy to clean so you don’t have to worry about any part molding. Water stays cold for hours. Definitely leak proof. And the design hasn’t faded off. I wash mine by hand so they don’t leave an odor but I do know some people who put them in the dishwasher and the silicone part leaves an odor and soap taste. I’ve thought a few of these water bottles. Love them. ... show more

    • Perfect for my Bluey-loving toddler
Color: Bluey Size: 12 Ounces
My two-year-old loves this water bottle. It has an easy-open lid that she can open with the click of the button and then close by herself. The handle is convenient and lets her carry the bottle. It is very easy to take apart the lid and straw to wash them. Added bonus is that this water bottle is dishwasher safe. It has been used and washed heavily and there are no signs of the sticker pealing off. The size of the water bottle is also great, not too big or too small. My daughter drinks water like it's her job so the smaller cups won't cut it any more which is why we like this size. Such a cute water bottle too, as my toddler absolutely loves Bluey! The cup does a decent job at keeping liquids cold. It will keep her water cold throughout the day; however, any ice leftover is melted by the next morning. We will definitely be looking to purchase another water bottle in a different design. ... show more

    • Super Cute & Keeps Water Cold — Just Needs a Few Small Improvements
Color: Bluey Size: 12 Ounces
I bought this Thermos water bottle mainly because of the Bluey design, and it did not disappoint. The colors are super cute, and it quickly became my kid’s favorite bottle. He actually gets excited to carry it to school, which is always a win for parents. The size is perfect for little hands, and the built-in handle makes it easy to carry around. One of the best features is how well it keeps water cold. Even after several hours, the water is still nice and cool, which is great for school days or outings. The bottle also feels sturdy and durable, and it has already survived a few drops without any issues. That said, there are a couple of things that could be improved. The closing mechanism could be a bit more secure — sometimes it feels a little too easy for kids to open, and I worry about accidental spills in backpacks. Also, I wish the straw was silicone instead of plastic. A silicone straw would feel softer, safer, and more comfortable for kids. ... show more

    • Great bottle
Color: Gabby's Dollhouse Size: 12 Ounces
I bought this THERMOS FUNTAINER water bottle for my granddaughter, and she absolutely loves it! She's a big fan of Gabby's Dollhouse, so she was excited the moment she saw it. The bottle keeps her water cold for hours, even when we're out running errands or spending time at the park. It's the perfect size for little hands, and the flip-up straw is easy for her to use on her own. It also seems very durable and has already survived a few drops without any issues. Cleaning is simple, and the lid seals well without leaking in her backpack. If your child or grandchild loves Gabby's Dollhouse, this is a great-quality water bottle that they'll be excited to use every day. Highly recommended! ... show more
