I feel as though I've asked this questions before, but for the life of me I can't find the thread.
Does anyone know of a specific (brand/style) bottle brush that will fit the Medela collection bottles? Nothing I do seems to get them all the way clean. It may just be me, but I'd feel better if I had a brush. I bought a Phillips brush, but it was designed for Avent bottles (which I don't have, so it's free to anyone who wants it - PM me) and is too big for the Medela ones.
