may be a dumb question but how do you do it. i just push the milk all the way up to the nipple if full with milk. is this right? don't want to put holes in it.
You're supposed to use them as-is. They're designed to work by just dropping them in the bottle, filling them up, and feeding. We've used them for months and my LOs hardly ever spit up or get gassy.
Re: getting air out of drop ins?
I never get the air out when I used them..I didn't know you were supposed to!
Once I realized you were supposed to, I did one day but they had a VERY hard time getting the milk to come out...so I let the air back in.
They didn't get gassy though...

My MIL said to do this and when I did, it made it harder for them to suck and they didn't drink what they usually do.
When I use them as is, they work great.
