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

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 purchased these because I thought that these would fit on standard USA water bottles (like they advertised).But right after the item arrived and I tried to fit it onto a regular size USA water bottle, it does NOT fit. The USA water bottles rim are about 2-3mm too big for the AquaSip attachment part to fit at all. It would have costed me more money to return the item for a refund. So I ended up tossing these in the trash. Please do NOT waste your money on these, they do not work.I wished that someone had written a review on these when I purchased the item. There was no review when I purchased the item.Hope this will help save you money and headache.

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!!!

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.

This worked great when going to the beach with my little one, and just to keep in the diaper bag in general. Love the fact that it can be used multiple ways depending on the thread of the bottle

Purchased this for my 4 month old who, for some reason, always wants to drink cold water from a water bottle. He is now six months and uses them daily. Takes a little playing around with but once you find the right fit it screws on accordingly. I dont follow directions well and even i was able to figure it out. I can only vouch for member's mark water being a fit. He loves to drink from them because they give a good flow and he likes chewing on them because they get cold from the cold water and sooth his teething gums. The only downside is that the flow itself is a stream so if its turned upside down or tipped over it continues to spill out, so babies definitely need to be monintored with it or things will end up wet.

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 do not fit any of the water bottles I've tried putting the nipple on. It did fit a juice bottle but the nipple is far too soft and ended up with my baby having juice everywhere. My 6 month old did better and made less mess trying to drink from the bottle.
