Lifefactory Sippy Caps for 4-Ounce and 9-Ounce BPA-Free Glass Baby Bottles, 2-Pack, White, LF135009C6

This LifeFactory sippy cup top is exactly what we needed! It fits perfectly on our existing bottles and makes transitioning from a bottle to a sippy cup so much easier. The silicone is soft and durable, and it doesn’t leak, which is a huge plus!Easy to clean, BPA-free, and great quality—definitely a must-have for little ones. Highly rec

We have 4 kids, and in our experience, no kid willingly gives up the milk bottle. It’s major drama no matter what and requires you to stay strong. Ha! That said, we had an extra tough time with kid #4 who was refusing all types of sippy cups of milk. I finally re-bought some of these tops for the Life Factory bottles we’ve used for all our kids. She refused (as expected) and then got sick so I went back to the bottle top for a bit. Tried these sippy tops again about a month later and was able to switch over completely after a few days. We also use a straw water bottle for water - so we use this exclusively for milk.Pros: Fits the Life Factory bottles we already invested in. Easiest sippy cup top to clean - no hidden pockets/pieces for mold to grow!Cons: Yes it will leak/drip out the top if your kid turns it over (especially because you have to remove the silicone stopper for them to use it…so we just don’t ever use those). We have to put the milk away for later if she starts playing with it or trying to tip it/throw it as it’s not spill proof.

I’ve now had to order these tops twice in less than 6 months due to how easily they crack and break. Not only that but they only shipped one top in this two pack and are telling me it’s amazons problem yet amazon has their support listed to fix this issue. Very unhappy with this.

4 stars only bc I’ve used this product before and like it. I ordered these to replace my super old one that cracked and got lids instead. Nervous to reorder and have the same thing happen.

I mean, remove the silicone insert or nothing comes out! Lol these aren’t spill proof but they don’t leak when used upright or while drinking if that makes sense. If you turn upside down they will trickle water out as well as if they are on their side. These should be used with supervision if your child is like mine. He gorilla slams his bottles and he loves to pour water onto surfaces and even spit/leaks water out of his mouth onto his shirt so much I could die! But yeah it beats metal or plastic bottles. I prefer that it weren’t a plastic Sippy cap, but I can’t find anything better. The bottles hold up under pressure and all wash easy! Good luck!

These are terrible. Once screwed on, it is impossible for anyone, including adults, to get any liquid out. First, the silicon piece needs to be perfectly aligned, which is hard because it skids while screwing the top. But second, it cannot be screwed on completely tight, or nothing will come out. This makes it useless because our child unscrews to make a mess. Sucks because I picked the bottles for this reason. Very hard to use properly. But they do not leak, I'll give them that...

Love that these go onto the 4 oz and 9oz bottles we have, but they seem to crack easily as we dropped the bottle from not very far up and the plastic cracked. I purchased more, hope they don’t continue to crack :/

These are great for the life factory bottles. My toddler has no problem with the transition. So far no leaking
