Meds & Food for Kids has a very impressive YouTube Video, but I can't find much information on their reputation as a charity - nothing negative, but nothing positive either. They don't appear to have been rated by Charity Navigator or the Better Business Bureau. Guidestar has no rating, but does supply this mission statement for Meds & Food for Kids:

Severe malnutrition is the leading cause of mortality in children under five. Our mission is to save the lives of sick, malnourished children in Haiti through a proven program of medicine, education, and a fortified food product eaten in the child's own home. This peanut-based therapeutic food is ready to eat, requires no refrigeration, and contains significant trace minerals and antioxidants, accounting for its much better success rates compared to current World Health Organization recommended therapies. A cornerstone of our mission is to aid in the development of the Haitian economy by producing RUTF in Haiti.

Charity Navigator has a list of charities providing aid in Haiti, with ratings for each charity.
