Baby BuddyAquaSip Silicone Water Bottle Spout Adapter, Spill Proof, Reusable, and BPA Free, White, 2 Pack

At first I didn't know these existed until my sister told me about it. I purchased a pack and really liked them for when I'm on the go with my toddler. I have some in the car, house, diaper bag, and babysitter.they do tend to leak if tilted. The size is just like a regular nipple bottle

They did not fit any water bottles

These would be great if you can find water bottles they fit. I tried them on the bottles pictured and they do not fit. I read the reviews and saw where someone flipped the nipple and used opposite side (it's a different thread), that did not work either.

Love these. Handy when traveling on the road or just to family members' houses and restaurants. Until my little guy can learn to adjust to the faster flow of a sippy cup adapter, this is perfect! Works perfectly on Poland Spring bottles. The lip that sits around the top of the adapter (the screw part), keeps the nipple from leaking where it sits in the plastic screw part. Like all bottle nipples, though, this will leak if the child up-ends the bottle and presses the nipple down/folded over. My son likes to play with the water bottle as he practices his gross motor skills, and if I'm not paying attention, he will end up with a ton of water on him from pressing the nipple and bottle upside down into his belly/chest. Also, if he holds it upside down, but not pressed against anything, water WILL stream out of the nipple. A couple of times, he's surprised himself by squirting himself in the face this way.

I'd give it 5 stars but when it's turned over it leaks out of the nipple and makes a mess. My 9 month old still loves it though. Oh, and to get it to fit on a Costco water bottle, just take the nipple out and flip it the other way. Easy peasy.

These were a life saver for traveling. Just make sure you bring something with you to measure the water if you are making formula. I'd measure out the water I needed, drink what was left, add the formula & voila. No trying to wash a bunch of bottles in a hotel sink at night or carrying a bunch of extra stuff while sightseeing. They were amazing on our cruise. We were able to use them on maybe 8 or 9 different brands including the local brands in the Carribean. You have to just figure out which side of the plastic to use & wiggle the nipple to fit, if you have any sealing issues. We didn't have any water bottles that didn't work. I read all the reviews before. I think maybe people that didn't have luck, just weren't patient to try the different sides properly. Happy travels!!!

I use these nipples for bottle baby goats. They are very soft and supple. Even the weak kids that are having a rough start latch right on to these nipples. I have used them on lamanchas, boer, Nigerian dwarfs, and mini lamanchas. The mini goats have no problem using these nipples even tiny goats that weigh less than a pound. I gave my friends, that raise goats, some of these nipples to try, and they are all hooked on them too. These are a lot easier to get the babies to take than the Pritchard nipples.

Cheaply built don’t last long works well 1 or 2 times then seem to rip

Llego en el tiempo prometido, muy útil aunque no se ajusta a todas las botellas, pero estoy muy conforme, lo volvería a comprar

Super utiles para cuando andas en la calle y no traes biberones, la tetilla es super suave a mi bebe le encanta
