Has anyone used the perfect prep machine for their second baby? Our DS is 3.5 and we're expecting our DD in a month or so. The machine was a life saver for us with our DS and I'd like to use it again. I plan on sterilizing it using the method on the TT site, but does anyone know of this is enough? It's been in our attic for the last 2 years and I'm worried that sterilizing it won't be sufficient to kill any nasties on it?
