Beautiful stainless no drip kids tumbler
[This review was collected as part of a promotion.] This is the Grosmimi stainless kids tumbler. It holds 10 ounces of hot or cold liquid. I got this in the butter bear pattern and it is adorable. It is suggested for 15M+ and that is what I would suggest too. It has a small pour hole so it helps little ones control the amount of liquid pouring out. The handle is perfect so your little one can enjoy carrying their own drink bottle. There’s also measuring marks on the inside and the top snaps tight so no leaks. Because it is stainless it keeps drinks super cold and will also keep liquids warm. All the parts are easy to wash which I love, no small parts to struggle to keep clean. Love this cup will definitely buy one for each of the kids as a Christmas stocking stuffer!

Great quality and truly spill-proof!
[This review was collected as part of a promotion.] I'm really impressed with this Grosmimi Stainless Steel Kids Tumbler. The design is even cuter in person-the little olive print has a subtle sparkle to it that makes it extra appealing for kids. The stainless steel feels high quality, and the flip-top cap really is leak-resistant. We've had zero spills, even with a two-year-old using it! It works perfectly for both my two-year-old and my six-year-old, which is a huge bonus. The handle is very sturdy and easy for little hands to hold, and the size is just right for outings, school, or keeping at home. Definitely worth it if you're looking for a durable, spill-proof kids tumbler that looks adorable too!

A must for toddlers at daycare
[This review was collected as part of a promotion.] This is a cool bottle! My 4 year old needed a bottle for daycare and what drew me to this one is the drink spout, which is ergonomically designed for easy drinking, and the fact that the lid is fully sealing with the very secure lid. It clicks closed and is not going to spill! The handle is also really nifty, it rotates around the bottle instead of being stuck to it in one position so it makes it really easy for my daughter to carry. Of course the quality stainless steel is a must too. I am glad I got this.

Great toddler stainless steel water bottle
[This review was collected as part of a promotion.] We love this stainless steel water bottle for my toddler! It has a very easy to use push button to open the lid. The spout to pour and drink the water out of doesn’t come out very fast, so it is manageable for him to drink it without a straw. The bottle is easy to assemble, and also easy to clean. The bear print is very cute and stands out from other water bottles so we know it’s his!

Cute, functional, and built to last
[This review was collected as part of a promotion.] I have gone through so many different water bottles with my preschooler and I realized over time how it is way more efficient and cost effective to just get a high quality one that is truly leak proof, easy to clean, and built to last. This water bottle fits the bill. I also like that it’s not a sippy cup. It has a drinkable lip and no hard to clean parts. It’s also high quality stainless steel and a very cute dainty design. Love this for my daughter and wish I had gotten it earlier.

Children’s stainless steel bottle
[This review was collected as part of a promotion.] I really like this stainless steel tumbler because I feel like it’s easy to clean and it doesn’t have any type of milk residue. I also like that it has a controlled flow because my young child is transitioning into these types of bottles and this one is great at 15 months. It also has a strap and my child LOVES to hold onto his own cup and carry it around. This cup also has a silicone cover for the bottom to protect from damage.

Stainless Steel, Great Design, Easy To Hold
[This review was collected as part of a promotion.] This is a water bottle for toddlers. It is not very wide. The kids can get their hands around it easily. The stainless steel keeps water cool for long periods of time so this is great for using throughout the school day. This belt makes it so children can drink easily without spilling water everywhere . The water bottle holds 10 ounces of liquid and it is easy to wash with a cleaning brush.

Easy To Clean Stainless Steel Water Bottle
[This review was collected as part of a promotion.] This is a really nice high-quality stainless steel tumbler. My kids have been using it for about two weeks and they really like it. It keeps their water ice cold all day at school. The handle is cute and makes it easy for kids to carry their own bottle or hook in a cubby. We own a lot of stainless steel kids water bottles and many are difficult to take apart to clean, especially the mouthpieces. This bottle is so easy to clean, all the pieces come apart and it is dishwasher safe.

Adorable and well-made kids water bottle
[This review was collected as part of a promotion.] This is a very nice kids water bottle! It’s really nice that you can take all the pieces apart making it really easy to clean. It is designed very well with seamless stainless steel. The printing on it is very cute and well printed. It pours out very slowly, which is nice for children just learning to drink from a cup and without a straw. I would definitely like to get more of these for my other children.

Perfect Size for Backpack Bottle Pockets
[This review was collected as part of a promotion.] This isn’t a really nice stainless steel water bottle. I know it is for children because of the easy drink spout but honestly, even an adult would enjoy this bottle because of how luxurious it looks the cherries that are painted on our beautiful and the bottle gives a very high-quality look . There is a silicone handle that can be attached to the bottle if you want to be able to hold it that way otherwise I like to leave mine off so it fits in my daughter’s bag easily.

Perfect Water Bottle For Preschoolers
[This review was collected as part of a promotion.] This is a great water bottle for children. It’s really good for kids. Those are not used to drinking out of the skin because the area is flexible and has a small space for where the water comes out so there is less spillage. There is a handle that you can use in the silicone is very soft . I like the colors of the bottle and the quality of the stainless steel of the bottle is impressive.

Stainless Steel, Durable, Easy to Clean!
[This review was collected as part of a promotion.] I really want to LOVE this bottle because on paper it has all the things to make it perfect — stainless steel, flip close, easy to wash, cute design options, and durable! I’ll have to settle for just REALLY liking it because it doesn’t have a straw, so it was very difficult for my 15 month old to properly use without spilling, even though the manual says use for kids 15 months and up.

Adorable and great design but a high price point
[This review was collected as part of a promotion.] First of all, let me just say how cute this water bottle is. The print and the overall design are amazing! I like that it is a controlled sip style. My son tends to drink out of that style better. The handle is so great for carrying and I love how the mouth piece detaches for easy cleaning. While all of these things are great, I don’t think anything is “standout special” at this price point. I could get similar quality at a much lower cost.

Beautifully designed stainless steel tumbler
[This review was collected as part of a promotion.] This is the most adorable simple design for a children’s cup. The cup itself is very sturdy and a great size for a younger kid. I like that it’s a spout and not a straw to help my baby learn how to use an open cup. It’s designed to have a slow flow which is perfect for my 20 month old! The rubber padding is great to help prevent any dents or scratches. The handle is also a great feature so she can carry it around wherever she goes.

Adorable cup for my lil guy
[This review was collected as part of a promotion.] This cup is CUTE! It’s such a cute little cup for kiddos with all the bells and whistles. I love that it comes with a strap to carry as well as a cover for the bottom up the cup to protect it. The design on the cup also caught my eye. It’s nice and neutral but so adorable. I wish it had a straw function as well but only that’s a small thing. The cup is great quality and my kiddo loves it.

Stainless steel kids tumbler
[This review was collected as part of a promotion.] I love this tumbler for many reasons! The biggest plus for me is the stainless steel material which will keep water cool for longer. It is also a safer material to drink water from because it will not leach chemicals. I also love the blush pink color and the cherry design with subtle sparkles all around. The button to open the bottle is easy enough to push for a toddler. It is not marketed as spill proof and it certainly is not. But the simple design is easy to clean! I also like that the drinking lip is made from silicon! Overall really love this tumbler!

Last step before a “no lids” drinking cup
[This review was collected as part of a promotion.] This 10 ounce cup is wonderful! It makes my toddler grandson feel like he is copying us and drinking from a travel mug like we are. I’d call it the next step before using an open cup (no lid). The liquid stays cold for a long time. The cup won’t break or crack when it lands on the floor. The lid is not easily opened by little hands, which is a good thing. With no straws, it could spill easier. The handle allows him to take it on walks and we can all stop and take a sip of our drinks. We love the big kid feeling he gets from having the cup and mimicking us

Transition cup to help toddlers use an open cup
[This review was collected as part of a promotion.] I bought this thermos for my 3 year old son. It is very well built. He enjoys pushing the button to open it and carrying it around. I like that it mimics an open cup to help him transition away from a straw cup. The pieces feel easy to clean and high quality. I also like that it comes with a silicone boot so the bottom won’t get bashed up when it hits counters and other hard surfaces. It is an unusual and cool concept.

Solid design and great for new open cup drinkers
[This review was collected as part of a promotion.] This kids tumbler was a great investment for our family. I love that it is made from stainless steel and is a very sturdy design. It has a narrow open cup design which is helpful as we transition from straws/sippy cups to more open cup products. I like that my kid can drop this without me worrying about it spilling everywhere as the top is easy to close and seal. I also love the cute design options overall for this product!

Great quality, easy for three-year-old to use
[This review was collected as part of a promotion.] This is a very high-quality water bottle. It is very easy to take apart, clean, and put back together. I chose the olive theme, which is so cute and can be used for a boy or a girl. It was very easy for my three-year-old to use by himself. The sip lid is almost easier for toddler to drink out of. Water kind of pools in it and then he’s able to sip from it like that. The handle can rotate as you hold it, which would make it easier for a child to hold onto it.
