Formulas? My daughter has been getting Similac Advance with the Immune Support in supplementation since she was 4 months old. She is now 8 months old and we have just completed weaning. She will be getting formula full time now and at $26 a can for the Similac, and in light of the recent economy, my husband and I were wanting to try a store brand. Are they the same? Has anyone tried the Target brand? Do you like it?
