Who uses the Tommie tippie bottles with the anti colic valve?

The little bit you see in the picture there that looks like a hole. You literally just turn the it upside down and press it together to make sure the valve is not sealed shut if that makes sense x

I pinch the inside part with clean hands to make sure it's not sealed right before I use it

@Sunny I do pinch the inside part but what bits supposed to open up the part you pinch?

Or the top bit that you see in that pic

The bit you pinch should open

Oh it doesn’t open when I pinch it is it meant to open and look like a hole kind of open?

Thank you though xx

It’s really annoying! It’s that triangle but underneath and I just pinched it with clean hands. It seems to seal right back up after but I did it anyway as assume that’s what they meant !
