H.H.
My doctor told us to start my daughter on rice cereal at 4 months. She loved it. We moved on to baby oatmeal about a month after and now we mix Gerber 1st Stage baby food with her oatmeal two times a day. We started with sweet potatoes (she really enjoyed that), then moved on to squash and some fruit (pears and peaches). Give each new food about 3 days before introducing other kinds to watch for any allergic reactions.
Have fun!
