My daughter was breastfed for the first 7-8 months, but because of travel and other reasons switched mainly to formula.  This formula is formulated for babies 0-12 months and specifically advertised as Enfamil's closest formula to breastmilk.

I was fortunate in that my daughter was not picky about which formula brand she drank.  (Yes I've heard you're supposed to stick to one brand, but I would just get the one I could get the best deal on, which meant different types of Enfamil, Similac, and even the target brand once).  I liked this formula though because first of all, it was visibly different...
