Spill-Proof Water Bottle Spout Adapter for Kids - Water Bottle Adapter Toddlers and Adults - BPA Free Water Bottle Tops - Compact Silicone Sippy Cup Lids - 4 Pack Red Blue Green Yellow

These are very sturdy and easy to use. Works great for young children, although mine found out quickly how to remove it from the water bottle.Does not leak.

Stuff it in the water bottle, give it to the kid...

Love these! Great quality, easy use!You have to kind of shove it into a water bottle, but I think that's to do with so it doesn’t leak from the sides.Dishwasher safeBought these to get my toddler to drink more water and she loves them! I carry one in my purse and keep three at the house.If/when these stop working, I’ll definitely be buying more. Worth the money.

Figured we would try them and we LOVE them! My 12mo old LOVES water and wanted to drink from the bottle like we do. These bottle toppers work GREAT! EASY to use, pretty leak resistant (only issue was when used on a flimsy water bottle and the little one squeezed the bottle, but that's was only with that brand bottle of water). I would have given a 5 star had the top been a little stronger or more child proof. It didn't take our little one long to take the cap off on his own. So for after a few months of use he only takes the small cap off the top and hasn't been able to remove the entire topper. It is really nice to not worry about sippy cups on the road. We keep some of these in the diaper bag and we always have bottles of water, so we're good to go and the little one likes drinking like a grown up!

The media could not be loaded. These are absolutely perfect for on the go to keep in your diaper bag. If you have toddlers there’s are a staple especially if you’re the type that kind of forgets your babies sipping cups and bottles at home. You can grab a regular sized bottle and plop it on and go! I haven’t had any accidents with the kids using these in the back unless they squeeze the bottles super hard I can see it spilling, over all though, these are great!

These are perfect for water bottles when you want to be sure you can put them in a bag, drink from them, and have no leaks (plus, they're cute). They are washable and reuseable. Very handy device.

This really cool spout makes it easy for me to share my bottled water with my 8 month old baby without worrying about backwash getting in my drink.

They do the job but if you are wanting it to be leak proof not for you.
