Contigo Kids’ Leighton Straw Tumbler with Spill-Proof Lid, 14 Oz., 2-Pack

Yes these are drip leak proof. They are better than any other cups we tried. I do think they are more for older kids as far as ease of grip but the 18 month old is stuck with these for now. The container is so so big. I would apreciate an 8 oz size. I love them so much as an adult I use them. I feel good about leaving 2 filled up one around the house for a toddler to drink from during the hot summer. So far cleaning them is pretty easy. I use them also to slow down water so less choking as little one learns to drink from a straw. The speech therapist agreed they were good for his swallow issues

Best toddler cups I have purchased and I have purchased a LOT! They truly don't leak.

We’ve been using these for several months now and I’m honestly kicking myself for not getting them sooner! They’re the best! It’s basically leak proof. The only time I notice them leak is right after my boys take a drink and there’s still liquid in the top part of the straw above the leak proof part. It’s not enough to matter though to be honest. Both of my boys are fairly rough on things so I was worried about durability but these have exceeded our expectations so far!

My criteria for a bottle/tumbler was strict: Leakproof, toddler-proof, not a lot of fussy parts to wash, NO nooks and crannies that grow mold, and no issues with air pressure (which will force liquid to spurt up out of the straw when you put a lid on, and make it difficult to suck from, etc).These are as close as I can imagine to the above in existence— not utter perfection, but very close. Kiddo can turn them every which way, bang and shake, and they don’t leak. They only have 3 parts: (1) the lid, on which the drinking spout is completely fused; (2) a silicone diaphragm that fits up under the lid, which creates a seal between the cup and lid, and has a spout that the straw fits into. That spout has a valve that only allows liquid through when sucked. Lastly (3), a hard plastic straw. No nooks and crannies, hallelujah! So far we’ve gotten everything quite clean in the dishwasher, though mayyyybe the valve or straw may occasionally benefit from a soak or a quick brush with a straw cleaner (not included). A tiny air vent hole in the lid and corresponding one in the diaphragm relieve air pressure perfectly (make sure they are aligned or it’s less effective).My 2-year old is a typical experimenter, so if there was a great way to get a lot of liquid out, he would have figured it out. The two weaknesses I’d identify are (1) the seemingly unsolvable problem: you CAN still spill any liquid that is sitting IN the straw above the valve— about a teaspoon? All toddlers think this is awesome and will work to dispense it. If there is a design that prevents this without causing the aforementioned nooks and crannies or air pressure issues, no one has yet figured it out. (2) I do wish that the lid tightened a little harder. It has a stop point, which may be to prevent damaging the silicone diaphragm, but I’d like it just a liiiiitle tighter. My kids’ hands are way too small to get the proper grip on the lid, but otherwise I honestly think they might be able to muscle it open.What caused it I don’t know, but once I had two of these that fell to their sides inside a lunch bag and over several hours leaked more than I thought they could. So I’d say only store them UPRIGHT. So maybe not the cup to toss into a beach bag, but SO great for everyday use, for liquids other than water, to use in the car, etc. Huge win!

This cup hits all the yes marks for me:-easy to clean with a sponge/bottle brush and a straw cleaner-little to no leaks (the straw does hold a small amount of liquid post drink that can spill out)-the leak proof mechanism doesn't come loose when the cup is dropped/thrown-easy to pull the liquid through the leak proof suction-can be used with or without the inner straw for kids who haven't grasped holding the cup down to get a drink-the straw can withstand biting and chewing-holds up to being chucked at the wall and out of the stroller very well

I love these cups! My 16 month old will only drink from a straw cup, and these are the best ones I've found. They're very easy to clean, and easy to drink from. And they do not leak! They can be thrown in the bottom of the stroller, tipped over on the couch, or held upside down, and they don't leak. They hold a lot more than he needs at this point but he can still carry them around with ease.

I bought these for my toddlers and they are durable enough to hold up to daily use. My toddler boys are rough on cups and occasionally throw them and our cups are still spill proof. I appreciate that the cups come apart easily for cleaning and are dishwasher safe.My only complaint is that the bottoms of the cups are too wide to fit in cup holders, but otherwise we love them.

I just recently got the Contigo Kids' Leighton Straw Tumbler 2-pack. They have been such a lifesaver for spill-proof hydration! Each tumbler holds 14 ounces and has a secure, spill-proof lid, keeping drinks in even with accidental tipping. The soft, flexible straw is designed specifically with kids in mind, which makes it very friendly for little mouths and teeth.These tumblers are durable and dishwasher-safe, adding to their best feature: easy cleaning. My kids go gaga over the colored designs, and so do I, because at least they get hydrated around here sans spills galore. The compact size fits right in the car's cup holders for travel or school. If you're in the market for some practical and fun kid-friendly cups, this Contigo set is well worth it. It has been a worthy investment for our daily family grind.
