We were unable to use the Similac Organic as it was cow milk derived... and our daughter could not tolerate it. We were primarily breastfeeding, however when I became pregnant with my second at around 6 months it became necessary to supplment... we eneded up using soy formula and she did just fine.
Beaudroux's Butt paste we found to be the most effective... and we quit using wipes all together and used water and a wash cloth... it did increase our wash load, but it was worth it for her hurting little bottom.
