I use formula and I never shake the bottle after the hot shot. I also swirl the bottle round and round which stops any thing getting to the teat
@Karlie Yep I do swirl round I always have done but still seems to be happening. I wash everything properly, sterilise and then make the bottles up as you're supposed to ??? It's baffling me lol xx
There’s a handy group on Facebook called Kendamums that has some posts on about this x
From my personal experience this has happened to me when I add the powder hot or cold, and I shake it straight up into the teat. Instead of doing this try swirling it in circles until the powder has sunk into the water, then give it a good shake. This solved the problem for me x
