Do you feed your child with cod liver oil? It's supposed to be good for brain development. However, my toddler doesn't like the taste (and smell)? How do you encourage toddler to take code liver oil? Or is there any substitute for the same kind of benefits?
MY friend found it effective in strengthening her child's immune system. She gives her boy Scotts Emulsion Original and did not have any issue with the taste. I think you can try adding it to milk, honey or syrup for your child.
