The average weight for a 2year old boy is 12.2kg, so you can see that your son's weight of 9kg is very low indeed. In fact his weight is below the lowest line on the children's growth chart. This together with him always being ill is a cause for concern.The diet that you are giving him seems to be quite good,but he is obviously not eating enough.Part of his problem may be his milk and dairy allergy and he may also have other food allergies which have not been diagnosed.Your son has asthma and this is further proof that he needs to be properly tested for allergies.I suggest that you take your son to be seen by a paediatric allergist and he will also need to be seen by a dietician with experience in children's allergies.There are experts in all the main centres in SA.
