My FAVORITE sippy cup for transitioning my toddler!
I was in the market for some toddler cups since my little one needs to transition away from bottles. I bought a couple different types but these Zak cups are BY FAR my favorite! They were highly recommended by a lot of parents and specialists on TikTok.The price is fair for the quality of the materials. I got the set with a steel tumbler and a plastic cup so I could compare (and avoid plastic when possible). They are both high quality, super easy to wash, are dishwasher safe, and the designs are exactly as pictured.My daughter does really well with these, and the straw top is a soft silicone so she gets to teethe on it too. I usually don’t add the plastic straw because my kiddo likes to tip the cup back like it’s a bottle. These cups are pretty leak-proof! She can spill an occasional drop or two here and there but it’s no different than how much she would spill with her bottle.The only thing that I can call a con is the fact that these don’t have handles, which I think would make it easier for my kiddo to hold, but she manages fine without them for the most part. Also, the steel tumblers are heavy and could do some damage if dropped on a foot or flung into a wall (she’s in a throwing stage) so we only use them with close supervision.If you are looking for a cup to transition your baby away from bottles, I would definitely recommend these! So far, these are my daughters (and my) favorite cup. I have already bought 2 more sets.Hope this helps!

Favorite Cups
These cups are my favorite cups for toddlers. I prefer the metal ones to the plastic ones because they keep the drinks cold. My son loves all the different designs- we have several. They do not leak and it is hard to find a cup that doesnât leak! Super easy to clean as well.

Want ten more
These are spill proof, the color hasnt faded at all..they are super cute and durable and they function well once the kids figures out how to use it. They are also great cause they hold temperature. Whether warm or cold they will lock it in for a while.

Must have for little ones
These cups are adorable. My toddlers love them. The size is great and easy for little hands to hold. So far no leaks which is a major reason I gave these a try based off the glowing reviews. Theyâre easy to clean too! I canât say yet about the integrity of the exterior but they do look just like the photos.

Nice cup but came damaged.
I love these cups but our lid came damaged. The vent area is damaged and causes the bottle to leak everywhere.

Toddler Must Have
I have purchased a few different straw cups for my toddler and thus far, this has been the game changer. This combo pack of a stainless steel tumbler and plastic cup is perfect. The tumbler keeps my breastmilk warm or her whole milk chill while the other cup is for water. She has thrown the cup, shaken it while it is upside down and literally NO LEAK. The flow of the straw is great and she does not have work extra or take in too much at time. 10/10 recommend, it is mama and toddler approved.

Best cups
I’m so happy I bought these cups!! Really good cups good quality you get 1 plastic cup,1 metal cup, and 1extra straw, and they have the bluey characters on them. This is a little personal but if this review can help anyone raising a kid on the autism spectrum or around kids that are autistic with sensitivity problems or eating sensitivity problems these cups might help they have helped my family. I bought these cups for my daughter she has autism and has severe sensitivity and eating disorder problems. When it comes to drinking and eating it’s hard to switch anything with her. I’ve been having really hard time and getting her off sippy cups she likes routine if you change anything she struggles with it. I haave spent over $150 over the months on different cups from other brands so many cups she’s had problems with all of them. I got these Bluey cups and she’s starting to use them because I can take the straw out it doesn’t leak (well they haven’t leaked for us) it has helped so much. She always trying to hold her cups up like she does with her sippy cup that’s where we run into problems because they will leak and she freaks out when her clothes get any things spelled on them and she just won’t drink anything. I have not had that problem these cups they’re amazing and the cups don’t look like a baby sippy cup they just look like a special water cup. Sorry for the long personal post I’m just very appreciated of these cups I’ve been trying for so long and too finally found something she likes is amazing. So I 100% say these are amazing If you read this I hope it helps you.

Easy to wash, most importantly it doesnât has hard to reach areas unlike my previous cup where mouldâs started to grow. Like that the straw is safe from childâs chewing as well.
