Baby Rice, Noodle & Porridge

What should I do when the kid is around 6 months old and some nutrients in breast milk are clearly not keeping up with the infant's growth and development needs? It would be fantastic if there was a food that could not only complement these nutrients but also did not influence the baby's digestion, thus nutritional rice noodles were born.
The first non-liquid supplementary meal introduced during the transition from breast milk to solid diet for adults is nutritional rice noodles.
