You know the wee travel pots for measuring formula? They're very hard to dry after they've been sterilised (without using something thatr isn't sterile like paper towels!) Is there a problem with not sterlising them? Also- the tommee tippee bottles we bought hold the water and the little pot inside them. Would that not make the cooled boiled water less sterile if the wee put was touching it?! Confusion....
