Munchkin Mighty Grip Trainer Cup 2-Pack, 8 oz, Colors Vary (Discontinued by Manufacturer)

After damaging the spouts from vigorous cleanings with a bottle brush I realized the key to keeping this otherwise perfectly designed sippy cup from the trashcan is just to be gentle when you're cleaning it. Only use a soft sponge and do not force it too far up against the top of the spout. The spout works by having three slits in the silicon and if one of those fragile pieces tears, you will have leaks. Additionally, because there is no valve, if your child is accustomed to biting the spouts this design will cause more liquid to flow more easily which can be annoying to them or something fun to play with instead of drinking. For my daughter this was not an issue and she loves the soft feel of the top. They quickly became her favorite. I just wish they sold the soft tops separately so I could replace the ones I've damaged. Such is the cycle of production and consumption I suppose.

...and that's that it's BPA-free. Other than that, it was a big disappointment for us. We were looking for some new sippy cups for our toddler, and I ordered this one on a whim. I wish I hadn't. It leaks easily when turned over, it doesn't have a lid to cover the spout, the handles are spaced so that my toddler pinched her hands grabbing the bottom of the handles, and it's a pain to get the spout off and back on for cleaning.I would've given it just one star, but I did like the fact that it was BPA-free.I like other Munchkin products, but not this sippy cup. We went back to our Born Free sippy cups. They work much better.

My daughter has become dependant on these cups. She will drink other fluids from any other cup but for her milk or smoothie she will cry if not out of this cup. I can not find these in the store any more so thank goodness I can find them here. She is 20 months so I don't want to be too harsh with her right now & tell her to learn how cope with changes life throws at you. For now I will apease her & let her be a baby for a bit longer. I gave it four stars because lining up the nipple can be a pain but I have mastered it & I can not find replacement nipples hence why I have to keep hunting down new cups. Also liquid will pool at the top & will splatter when the cup is dropped but they make my little girl happy.

This was a great first sippy cup for my little guy. We cycled through quite a few, actually, before finding one that he would use. The nozzle is soft and easy to drink from while still being (relatively) spill proof (we'll get to that later). The handles are easy to grip. And it's dishwasher safe! There aren't a lot of edges and bits for gunk to get stuck in, which is nice.The only reason why I'm docking a star is because after repeated use and a fair bit of chewing, the nozzle starts to fall apart. One of the cups started leaking, and of course, this makes me worry a bit about the little pieces of plastic that are probably coming off. And once the nozzle was nice and soft, little kiddo figured out how to squish it against his tray and make a personal splash pool. That's when we transitioned to straw cups!

Our child used silicone nipples on his bottles, so these Munchkin cups were a great transition for him. They are really easy to clean, and because the top is clear you can easily tell if the surface your child is drinking from is clean, mold-free, etc. This was a huge plus for us. In addition, the cups are very light and small enough for his hands. I like that the straps that we bought for his sippy cups stay on these so well, too - some cups are not contoured enough for the strap to remain secure. I think this is a well-designed and affordable product.Our child started using these when he was about 9 mo. old, and he is still using them nearly a year later. He developed a lot of teeth pretty young, and he does occasionally chew on the silicone valve, or pull the cup out of his mouth with his teeth clenched which you would think would be hard on it, but we have seen no sign of tearing on the silicone surface. That is not to say it couldn't happen - it just hasn't been our experience. However, I think it would be a very good idea for anyone using a silicone product with a toddler to keep a close eye on the wear and tear, and not let them use it for teething.We never put these in the dishwasher. I am not sure if that makes a difference, but I don't like heating up plastics to high temperatures then eating and drinking from them...even if they are BPA free, etc. YMMV, of course.

When they first arrived, my 1 year old loved them. Within a week of using them, they started leaking. It didn't start at first, but within using it for few days I started noticing my lo pants wet in the car seat. First I though he wet himself, but than I realized, it is the cup. Not just one, both of them. Very disappointing, since Munchkin is usually my brand of choice.

My daughter was very good at seamlessly transition from nursing to bottles on any given day and was happy to drink water out of several different sippy cup types including Camelbak bottles with the bite valve. As a result, we didn't give much thought to the transition to sippy cups for milk only. We thought she'd be fine drinking her milk out of any of the cups (and made mistake of not introducing milk in sippy cups occasionally before making the switch). We went cold turkey on bottles to sippy cups when she was 13-months. This didn't go over well until we realized she was willing to drink milk out of these cups. I think they are more similar to bottle nipples, which is why she likes them. I highly recommend for anyone else experiencing difficulty making the bottle to sippy only for milk transition.When tipped upside down, these don't spill, which is great. However, you do have to make sure the plastic spout top is completely in line, or milk will leak. Also, make sure no liquids are on the inside tread, or that will leak out when tipped. My daughter does chew on the top a bit, which we try to prevent, and hasn't yet bitten through in about four weeks of using two cups, twice per day. Hopefully that won't happen.
