thinkbaby Thinkster Straw Bottle, Light Green/Green, 9 Ounce

i've tried pretty much every cup on the market and this is the one i've chosen for my (now) toddler. i intro'd this to my baby when he was 6 months with water (never gave a sippy cup, i went straight to this straw cup). here are the pro's and cons:PRO's:-easy for baby/toddler to hold. the handle doesn't have to be in a specific position for baby to get the milk out. it kinda swivels and adjusts to the baby-easy to clean but you need to buy the skinny bottle brush to get inside the straw-does not leak when you hold it upside downCON's:-ive had to replace one because of mold, but all cups develop mold, i've found. you just have to take the straw piece out in its entirety a few times a week and clean thoroughly-there have been a few times where the milk spatters out when i open the cap. not sure if it's due to temperature of the milk?-my child has dropped this so many times and for the most part it doesn't leak, but it will sometimes. not fool proofit took my baby about 3 weeks to really learn how to drink from this straw. just STICK WITH IT and don't give up! i wouldn't recommend giving a sippy cup, you'll have to eventually wean the child off of it and it's probably more difficult to do it later. just intro the straw cup from the beginning!

I have four of these straw bottles in different colors. We tried at least ten straw cups and this was the only one my son would drink milk out of without massive spills occurring. He occasionally throws these bottles to the ground, but we have not experienced any cracking. I like that the replacement straws are easily accessible and that the bottle has a removable hand hold. Replacement straws can be found here:  thinkbaby Thinkster Replacement Straws, 3-Count . We have also not experienced leaking with these bottles, which has been a problem with quite a few of the other bottle options. The biggest challenge with the option is that you have to have a very thin brush to adequately clean all of the straw components. The straw piece that pokes out of the lid can be removed for cleaning.

Great cup. Yes some squirts out when there is backup liquid in the tip, but nothing is perfect.However.... Do Not use this as a water cup on an airplane for your child!!! I opened it up after we were up in the air and the pressure from the plane had it shoot a stream of water across the isle and into the face of anothe passenger, for several seconds while I fumbled to get the cap back over the straw/spout! Honest mistake. And all planes have pressure. Just use another cup while flying.

I loved the concept of this sippy cup for my 13 month old son. We got this cup, because he was done with bottles, but was lazy and wouldn't lift his arms enough to drink from a sippy cup. He drank from straws at his preschool, so I researched different straw cups to try to find one that didn't leak. I had previously bought the Take and Toss straw cups with the lids, but those leak from the straw once they are tilted or turned upside down.I saw the Thinkbaby straw cup and loved that it claimed to be leakproof and you could cover the straw when traveling. The first week we had this cup, I was impressed and it didn't leak at all. I loved the handles, which made it easy for my son to hold. It is relatively easy to clean, but I have to use a bottle brush, the nipple brush that comes with the bottle brush, and a straw brush, which can be time consuming, but that's what I get for going with the straw cup. I also bought the replacement straws for this cup, since my son likes to chew on everything. The initial straw lasted about 3 weeks before he chewed through the tip.My son likes to throw everything on the ground, so I will say that this cup held up to the abuse for a little while. I think that's what started the cup to leak after the first week. It would just leak a little bit out of the straw when tossed on the ground, but slowly it started to leak more and more. Every time I would flip open the straw, milk would start shooting out from the straw due to the pressure build up. It occasionally leaks from the rim of the lid as well. So I can't say that it is 100% the cup/straws fault, since my son did drop the cup a lot, but this cup just doesn't work as I had hoped. I did read other reviews that said the cup held up well after their toddlers threw the cup a lot, so I might just have a dud. Not sure if it's worth contacting customer service about. We still use it, but I constantly have to cover the spout when flipping the top open to avoid a stream of milk and I have to unscrew the lid all the time, so the pressure doesn't build up. Just a big nuisance.Pros: easy to use, nice straw that is flexible and does a nice job getting all the liquid out to the last drop, and like that you can close the straw off with the swivel top for easy travel and no spillage when carrying or traveling with it.Cons: started leaking after 1 week of use, straw tip is very soft and easy to chew through if you have a kid that likes to bite on everything, and milk gets stuck in the littlest of crevices, so I have to use every brush I have to thoroughly clean the cup.I would not recommend this product.

We LOVE ThinkBaby cups! We prefer straw cups to avoid any issues with speech development and these really do the job well. Minimal issues with leakage (as milk gets closer to room temperature it works its way up and out of the straw, but that's with ANY straw cup). Our toddler loves to throw cups from his highchair and these cups hold up well to his abuse. We like the design and we introduced them successfully around 8 months. He took to them right away and made the transition from bottle to cup a breeze. We still use them as our main go to cup at age 16 months. Highly recommended!

Got the thinkbaby cup for our baby who was transitioning from the bottle. I had read that a straw cup was a good transition because straws helps develop mouth motor skills. She took to it pretty quickly. The handle is removable which is nice since she wasn't able to chuck the cup as far without the handle. I wash this cup daily and have a couple different sized bottle brushes, but have occasionally noticed some mold growing in the tiny crevices of the lid. Once I see the mold I can easily clean it. But it appears to grow in places that are not easily reached by the bottle brush. That being said, we now own two and they withstand a toddler knocking them off their high chair or chucking them to the ground.
