I’ve been looking for something that my 23 month daughter can drink out of that doesn’t contain any plastic but that would keep ghee milk cold and so far the Pura Kiki sippy cup has been almost perfect.Despite being almost 2 my baby is still nursing on demand. We’ve weaned her down some but she is still insisting on nursing to sleep at night and for any naps she takes. She also is still waking at night and wants milk before she goes back to sleep. (I know, I know Its my fault. I made the mistake of letting her nurse to sleep as a baby instead of letting her naturally transition into using her self soothing skills when they developed, So I’m kicking myself now that it’s too late ?)So anyway, I’ve been searching for a non plastic/insulated cup (but similar to a bottle) to start working on transitioning her from nursing to sleep (and getting her out of our bed) but I was nervous as She’s never taken a bottle before so I didn’t know if she would even try the Pura.At first she was a tad confused. She is used to drinking out of straw style cups so she wasn’t sure how to use this type of cup lol. But later that night when tired and laying down I tried again and she was able to drink from it pretty easily. While I haven’t been able to kick the nighttime boob yet, the cup has still been a worthwhile purchase.Pro’s:-The milk stays cold for hours-the colorful sleeve is WAY better looking in person then on the screen which was a pleasent surprise. The colors are quite aesthetically pleasing, and doesn’t look babyish with little characters or shapes on it like most cups so no one is embarrassed by using a “baby cup”, it passes the “cool kid cup” test and no one has died from embarrassment from being caught using it in public. ?- it doesn’t sweat and the sleeve provides a great grip. I struggled to get it on at first (I took it off because it wasn’t lined up properly and it drove me nuts), but once I figured out the trick to rolling it up the cup it was super easy to adjust. I was worried it would stretch or rip but it didn’t.-Also, the cup seems pretty durable. It’s been dropped a few times and no dents yet.-The silicone lid is easy to drink from and so far as been pretty durable as well. My daughter hasn’t chewed it up so it must be decent material.-the cover confused me when I was looking at it online, but as soon as I got it I realized how great it was. It stays on and doesn’t budge.-changing the lid as your kid grows or for older kids to use it is genius. I hate having multiple cups for each stage. Especially considering that I have 3 little kids using sippy cups.Con’s- only one really.The lid does leak. My daughter left it laying on her bed at a hotel and it leaked onto the bed ?I figured it wasn’t leak proof and I’m not bothered by cleaning up liquid leak messes (I have three toddlers, all born right in a row so I’m used to cleaning up after 3 leaking cups and find it easier to monitor the cups and teach them to keep them upright at a table most of the time, then to chase them down). But if that’s a deal breaker for you then the Pura isn’t worth the cost because it will leak if it doesn’t have the silicone cap on it.However, if you aren’t hung up on a little leaking when it use then this cup is well worth it. Especially because if you put the cap on and toss it in your bag it stays put and dry. And that’s all I care about (and if cups leaking in your bag is a problem you have get a jujube bag. Made for moms, doesn’t looks like a diaper bag so I don’t feel weird carrying it when I am kid free, and most importantly They wipe off almost all stains with a wet rag and are designed to be washed. Genius idea really and absolutely worth the cost with their amazing magic material they use).My apologies, I digressed a bit...Anywhoo, The price of this cup is a bit steep. My “first time mom self” would of handed out a major eye roll and probably kicked my butt for spending close to $30 for a sippy cup. BUT when you realize how dangerous plastic is and the cost of using it in practically everything we possess, $30 doesn’t seem so bad.Plus, i’m Over the whole “bazillion sippy cups and all their annoying pieces” crap. I despise having 20 different baby cups to wash and Keep up with. It’s the one place I really embrace the minimalism concept because I really just want one good solid cup for each kid to use while playing and when leaving the house and otherwise we can use half pint mason jars with a silicone lid to drink from at the table.So if you can’t tell, I definitely recommend this cup and am buying the straw lids for my older kids to try out. If they like it I’ll get them their own insulated cup as well.I’m even looking at getting the largest size for myself.
