Hi Milaners, water q for you: we are on the city, well, like most of Milan, and we do not have a water softener. One thing I’m worried about is sanitizing bottles or pump parts in the well water because I notice that there is sometimes sentiment in the water – I find it in the pet bowls, or in the bottom of our water bottles, sometimes as a film on top of our boiled water. Can this hurt baby? Google has failed me in this area..
