I've amassed a fair share of random bottles (Avent, Evenflo, Similac, etc) through clearance shopping, gifts, etc. Wondering throughts/experience on using a variety of bottles or if I have to shell out the money so all the bottles are the same? (One of my friends warned me about different nipples on the bottles and that babies can tell the difference between bottle brads?) Thanks for any advice!
