Hi, can't find the answer to this question. I have just had my 3rd baby who is 15 wks old. Since I had my 2nd in 2004 the guidelines for weaning have changed. My gut instinct is to do the same as I did with the other 2 children, but becasue they have changed the age from 4-6 months to 6 months I want to know why before I start introducing food to baby number 3. Anyone able to help?
