Dr. Brown's Milestones Insulated Sippy Cup with Straw and Handles, Spill-Proof Tumbler with Lid, 2-Pack, Green, 10 oz/300 mL, BPA Free, 12m+

Best sippy cups ever! We bought these because we liked the Dr Brown bottles and they were insulated, which we needed for a trip to Puerto Rico. There are pros and cons to these but- I feel like they balance eachother out and still give them 5 stars. The valves are a pain to clean if you let stuff sit in the cup. We usually rinse cups as soon as we are done so it isn’t a problem. However, we forgot one in the diaper bag. We simply soaked it in hot water and it was ok- but a lesson learned pain. If you child drops this from their highchair you will get splatter- the positive to this is that they do not need to bite the straw to get a drink which makes the learning curve less. The super flexible drink part of the straw can become a fun flicking game for your toddler. You can put ice water in this cup, take it out and about and still have cold water 5 hours later. We tested this before our trip.

Actually leak proof!! We have used these since 6 months, have had to replace the straw because it is silicone but worth the price!

LOOOOVE these cups. My girl is 12 months old and this is her favorite (we’ve tried them all). Leakproof, so easy to clean, and insanely cheap for the quality! Keeps her drinks cold and she can even easily use the slide lock feature herself. Absolutely love.

Updated : this is leakage proved. If you experience the leakage issue, make sure to check if your top soft straw is inserted into the hole on the lid completely. Pull that straw until you hear the sound. Since I figured my mistake, I had zero leakage problem. Another advantage of this product is, it was thorougly designed. For example, my son uses this for his night bottle alternative and sippy cup for hydration during the daytime. At nigit, I remove the long straigh straw so that the milk comes out while he laid down. During the day, I add this straw so that he can drink while he sits or stands. It is great, I am very satisfied. I like that this cup has many pieces separated, I can wash each part well for sanitizing. I also liked this product because it allows the thick beverage to go through the straw, such as smoothies or oatmeal with milk mixture. But it leaks a lot. It is not leakage proof, once the liquid comes out on the tip of straw. Lid for straw closure is structually not able to prevent leakage as well. Bit disappointed.

We live by these cups. The straw is easy to use for my little one. He was about 15 months when we got them and he can easily open and close the spout. The handles are great and the best part is they are easy to clean. The straw detaches and you can throw it all in the dishwasher.
