I used prosobee with lipil with my 2 1/2 year old. Initially I attempted to breastfeed, but at 7 weeks old, she decided I was not enough. We originally went to regular formula, but she projectile vomited that up. The pediatrician recommended the prosobee. She took right to it, with no problem. She was much more content and stayed on that formula until she was about 11 months old, then I slowly weened her off of it and on to regular whole milk. She liked regular milk fine and had no issues with the transition. She still a major milk drinker.
