Our expert says:
The average weight of infants of 1 year is 9 kg so your son is not really underweight seeing that he is not yet one year old. Because it is so difficult to select a diet that avoids peanuts, wheat, soya, cow's milk and egg white, I would strongly urge you to consult a clinical dietitian (visit the Association for Dietetics in SA Website at: www.adsa.org.za and click on "Find a Dietitian" to find a dietitian in your area). The dietitian will have to work out a special diet prescription for your son so that he is not exposed to the offending foods, but does still grow and develop normally.
