When it comes to formula, the first thing that pops into your mind should be "Is my baby getting the nourishment and immunities that he could be getting from breast milk?"

Buy formula in bulk, whether it is from a bulk store like BJ's or Sam's Club, or you could buy bulk online if you don't have a membership to one of these stores. The only problem with a wholesale club is that it will cost you $50.00 per year. Here are some online store prices.
