Why do bottles come in glass and PPSU? How to choose?

Both designs are identical, but glass heats milk faster while PPSU is lighter and nearly unbreakable – both are safer with heat than regular plastic bottles.

Why does milk leak when my baby sucks?

Warm liquid can build up pressure inside the bottle, ausing mik to flow through the nipple even without sucking. If this happens, unscrew the cap to release

What’s borosilicate glass? Is it better?

It’s extra-tough glass that handles sudden temperature changes better than everyday glass, so it’s less likely to crack.

What’s the warming base pad for?

It seals the bottle base during warming to prevent leaks – just remember to remove it before feeding your baby.
