Milk formula Clumping

Normally happens when the water in your baby's bottle is a little warm or when the spoon touches the surface of the bottle when it's wet. Just wash it off and dry it first before using it again.

From the looks of the clumping it’s just aggregation due to warm water vapour 😊 Simply wipe it off to avoid it going bad, as moisture enables microbial growth

It happen to mine too but dont worried it just clump and you just have to wash it away

What brand are you using. I haven’t experienced this before

try to keep your hands dry when preparing the milk

It’s ok .. no issue with tht ..

steam when put in milk bottle

sticking to water vapour
