A lot of reviews I’ve read seem to be user error. My 12 month old drinks from this cup very easily in almost any position and loves it. And after figuring out a few things, I think it is nearly perfect. Let’s clear up a few things other reviews have complained about, so you will love your new cup too. 1. It leaks/bubbles out cold liquid when taken out of the fridge. -This is not a design flaw but just a physics reaction. Yes, if you take the cup from the fridge to room temp, the cold air inside the cup expands as it warms pushing out a bit of liquid from the straw. Very simple solution is to simply unscrew the top for a minute (maybe less!) so that as the air expands in room temp, and liquid isn’t pushed up and out of the straw. Seriously, try it. Very simple solution once you realize why it is happening. 2. The valve in the straw make is very difficult to drink out of. -I thought this at first as well. Please do not cut the valve out as other reviews have suggested. The valve is meant to be compressed from front to back (top to bottom) as toddler is drinking, and once compressed slightly, offers nearly no resistance to drinking. When not compressed, keeps your cup leak proof. 3. Difficult to clean. -You can also compress this valve front to back, to insert cleaning brush provided and to allow water to rinse through it easily while cleaning. Knowing how to use the valve makes cleaning very simple. 4. Not leak proof when turned upside down. -I think this has to do with improper straw and stopper placement. You must pull the straw through until it clicks into place and make sure the stopper connected to the straw is firmly placed over the air hole at the top of the lid. Then, no matter how my toddler carries it around, it never leaks when upside down. Also, make sure the lid is screwed on until the handles click over the bumps on the side to lock it on. It is easy to not screw the top on enough if you don’t know it needs to click in place to lock. I’m sure a few cup will be made with defects and this won’t fix everyone’s problems, but I think a bit more knowledge of how to use the cup properly would solve most of the complaints listed about the cup. User error seems to be the biggest problem with these cups. The only minor draw back I’ve noticed is occasionally getting flicked with liquid when my son finishes drinking and flicks the straw out of his mouth at me. But I think that will get better with time. *Please don’t let the negative reviews keep you from buying and loving this cup. Just take a minute to learn how to use it to its best potential and I think you will love this cup too!

I bought this cup for my daughter when she began her transition away from a bottle around 11 months. There are some things to note about this cup so that it functions properly. First, the straw was really hard to suck through when I first tested it. However, YOU HAVE TO MAKE SURE THE DISPOSABLE PLASTIC COVER IS REMOVE FROM THE WEIGHT AT THE END OF THE STRAW BEFORE FIRST USE. Also, it helps if you roll the top of the straw where the valve is through your fingers a couple times to initially open the valve before first use. This is also suggested in the instructions that come with the cup and I think some people who left bad reviews about the slow flow of the straw may have not done one or both of these things. I myself did not do either before trying the cup the first time and I also thought it was impossible to pull through. Second, THIS CUP DOES LEAK A SMALL AMOUNT. The valve that keeps the milk from coming up from the straw is about an inch and half below the top. This means that any milk that is in the straw above this valve will leak when the cup is tipped over, thrown, or if the straw is flicked such as when you open the cup after closing it with milk in the straw. THERE IS AN EASY FIX FOR THIS. After your child is done drinking and before the cup is thrown or closed roll the top of the straw through your fingers, so that the milk above the valve can go back down. OTHER THAN THIS I HAVE NOT HAD ANY LEAKS WHEN THE CUP IS PROPERLY CLOSED. Third, I ended up ordering 4 of these cups for my daughter to use daily for the milk we send with her meals to daycare. Somehow, I received cups from two different batches or from two different manufacturers and the tops of two do not fit the other two and vice versa. This led to the cups significantly leaking from around the rim and I thought at first, they had warped in the dishwasher. IF YOUR CUPS ARE LEAKING AROUND THE RIM, PLEASE CHECK THE PRODUCT NUMBER ON THE LID AND CUP TO SEE IF THEY MATCH EACH OTHER. Apparently, Munchkin uses more than one manufacturer, and the products are not exactly identical. This is a little annoying, but I can live with it because overall the cups work really great for my daughter. The weights straw works great, and she has even leaned all the way upside down and still been able to drink. The straw is awesome verses a sippy cup because it is actually helping to strengthen the muscles, she will use later for talking. And the handles on the side allowed her to immediately be able to drink independently without any trouble at age 11 months. OVERALL, THIS PRODUCT IS GREAT. I HAVEN'T FOUND ANYTHING BETTER SO FAR!!!!

Excelentes vasos son perfectos para enseñar a bebé a beber agua , súper recomendados y excelente material viene con un kit para lavar su popote !

I am a new mom to twin girls and I used this cup for when they started solid foods to drink water from. (6 months old) They were able to learn how to use the draw very quickly. I really do like these cups, they come in fun colours, they don’t leak at all, they close well so I can throw them into the diaper bag and not worry about leaking. They do take quite of bit of work to make the water come out which is great for small babies so they don’t choke on the water. It is an easy transition from bottles to this cut. The weighted bottom makes it easy for them to always be drinking water and not sucking in air! Definitely recommend this product to all new parents with small children.
