i have the hardest time keeping LO's straws clean. i'll steam them every once in a while, otherwise i use a chopstick with a lil bit of paper towel to make sure there's no leftover milk etc. the nipple brush that we have is too thick!
i've thrown out two old bottles too because i just couldnt get the straws clean.
i've seen replacement valves, but no straws!?
what do you do?
