C.F.
I used Similac Sensitive for the first 5 or 6 months to supplement breast feeding, then switched to the Target brand formula when my son stopped breastfeeding. My son had absolutely no problems with the generic. I've used the Target brand formula for the past 6 months now. I would advise against Walgreens brand though. I picked it up once when I was in a hurry and it doesn't mix well and you end up with clumps that get stuck in the nipple. Frustrating...
