What are the bottle caps for??

[Lucinda15]

New to formula feeding. What are the bottle caps for?? I've never used them and wondering what I'm missing....

You put them on when you've made up the bottle to shake it without it going up the teat or spilling. At least that's what I used to do with DD1. I haven't used them with the others though.

Do you mean the little discs or the kids?

The discs are put in instead of the teat so that you can freeze/store milk with contamination.

The kids are to protect the teat from contamination and leaks.

*without contamination rather!

So you can use the bottle as a storage jar. I have never used them as the teat with the lid on works fine

Stops spillage if you're out and about with bottles in bag/pushchair/car.

I never knew and never used them!

Ok thanks everyone. I assumed it was to use bottles as storage jars when required. If I'm shaking up formula I just put the bottle together with teat and lid. But then wondered if I should be using the cap to shake up formula to prevent the teat from.... I don't know what! Lol! So thought I'd ask the wealth of knowledge that is mumsnet. It seems like too much of a faff to put the cap in to shake and then take it out and put the teat in. And on the go I make up bottles as needed so I'd rather not be faffing - plus the less handling of the teat/bottle the better I reckon. I am not sure I'll be using them much! X
