Thank you for your query.
I can understand your concern as a mother. Let me add that your son is doing absolutely weight wise and I do not understand why do you want him to be overweight
at a young age. You are giving him a good diet and should continue to do so. At this age milk supplements like Nido are not what the child should be having. He should be having a good nutritious diet.
As regards Irozorb, what is the haemoglobin
of the child? If it is low then an iron preparation is required. If the levels are normal then you can avoid the iron preparation. Apart from Irozorb there are other iron preparations available which can be tried.
I hope I have answered your query to your satisfaction. Feel free to revert back for any clarification that you may need.
Wishing your son all the best.
