For the case of my daughter, I tried to feed her when she was 10 months old but she was allgery to bird nest. Then I stopped it until 1.5 years old.
For the case of my son, I tried to feed him during 11 months old. He is doing quite good with that and his health is obviously improved.
Actually, my son got pneumonia before and a little bit anemia which is similar as Mediterranean anemia. Therefore, I want to feed him bird nest to improve his lung and health condition.
For my opinion, if it is not a must, better to feed him later. If you really want to feed him brid nest, give him 野生冇漂過果d should be better, less 雜貨
