Our pediatrician recommended starting at 4 months. With rice cereal, then fruits, then veggies. Every 4 days start a new food. I took it slow though, b/c I wanted to make sure my LO was getting all his milk and definately did not introduce new food every 4 days! I gave him few tsp. of rice cereal for like 2 weeks before introducing fruit, then tried new food once a week. My baby is 6 mos. old now, & has had rice cereal, apples, pears, bananas, sweet potatoes, butternut squash, oatmeal, peaches, green beans, carrots, & peas so far. (in that order). My Dr. says we can start on meat, but no more than 1 jar of meat per day. He still BF 4 times a day.
