Mind sharing the colour of Avent milkbottles ? And usually how many milkbottles will you be preparing for your newborn ?

I bought the natural bottles classic is discontinued alr) all in the clear series. It works well for my daughter since Day 1, no leakage or teats issue. I would think 6 bottles is good to start with since the sterilizer can only fit 6 at a time. Amazon offers it at a lower price, I actually bought difference sizes and the different teats all at once. I bought about 10 bottles and that's because I like to prepare more than needed. It's good to buy the newborn starter kit which comes with 2 newborn bottles and a few other accessories to try out first and see whether your LO likes it.
