Boon Snug Sip Universal Water and Juice Silicone Bottle Toppers - Soft Spout Conversion Caps with Spill Proof Valves - Silicone Bottle Covers for Travel - Includes 4 Bottle Toppers and 4 Cases

The media could not be loaded. Okay! Yay! So my kid is prescribed PEDIASURE and I've BEEENNNN looking for something that you can just pop on the bottles. She wont drink it from a straw so Until recently we just used the dr brown bottle neck rings with the sippy cup nipple/spout, but with her needing to take lunch to school now I wanted to see if I can find anything that looks less like a bottle. (I had no rush to ween her off, but im concerned her teachers mightve lol) anyway everything was either too small, like for water bottles or too big like for Gatorades and this fits the pediasure 8oz bottles AND she uses it. I saw a review that said these fit the milk bottles from McDonald's so I thought DING DING DING! I did slit the cross/openings with a Knife all the way thru the edge of the top for more flow, less resistance, therefor less spillage. Teach kids to bite first, then drink. They do spill if squeezed or if they don't let air flow in between drinks. Might also spill if not upright, but keeping them around and just swapping the tops out is fast enough so no need to have them on already to carry around. The little carrying cases are great too because I just throw then in her lunchbox and her teachers know how/when to use them. Literally obsessed with these. HIGHLY RECOMMEND .(Adding video of how I slit them a little more open, not a defect)

I would give a 5 if my toddler wasn’t a beast. Great universal cap, love that it comes with a holder for each one. Only dislike is my strong toddler rips it off and we are in the dumping everything out phase! But otherwise leakproof, easy to use, easy to clean!

My toddler loves these. They can have big kids cups now and doesn't get upset about having a small cup. No leakage, fits body armor, gatorade bottles, and more.

If your a toddler parent, you NEED these! they work on everything i have came across- i might have to cut off the little plastic ring that is left behind on the lid on mostly the larger bottles but well worth the little extra effort over spills. My toddlers LOVE them and perfect for car rides and traveling. I will add these to all my baby shower gifts as my useful gift!

My fiancé saw these advertised somewhere and wanted me to order them. I did and the very first time our son used one it made a complete MESS! Drink spilled everywhere! It was down on the bottle as far as it would go but it came off easily! I don’t drive so taking this to the ups store to send back is impossible for me so I’m just out the money. I don’t recommend anyone else wasting money on these bottle tops!

I like how this product does not leak, attaches easily to bottles on the go, and it’s fun for my toddler to use. The downside is that I have to monitor my toddler using it at all times because she can remove it easily.

These are so cool! We are often traveling and it's getting harder and harder to find straws to use in my toddler's drinks. These not only fit on common single use bottles, but they also fit on our narrow neck Nalgene bottles, making it easier for him to drink from what we already have. The cases mean I can throw a couple in the diaper bag just in case we forgot our reusable bottles or go somewhere that we can't bring our own drinks. The flow is pretty slow for an adult, but even I will probably use it on my Nalgene while driving so I don't have to take my hands off the wheel to unscrew the cap it came with!

These work very well for my granddaughter
