Is it ok to start baby food for my 5 month old?

Yes: The short answer is yes. Below is a link from the american academy of pediatrics that discusses the introduction of solid foods for infants. The current recommendation is that breastfeeding be the sole form of nutrition for infants until 6 months of age. That being said, each infant is different, and gauging readiness for solids is discussed in http://bit.Ly/wemygf.

I wait until sitting: Studies of various populations show that breast milk alone supplies balanced nutrition for the first year +. Most early solid feeding pressure comes from the days babies were fed home made blends of boiled cow milk/karo & vitamins.At the time early supplements made sense, now they are overdone.Starting should focus on training baby to sit up & eat in preparation for his/her position at the table.
