Should you go for a soy-based formula or a cow milk based formula?

In additional to what Idza has mentioned, another point to consider is the age of your baby. For babies below 12 months, regular milk formula is not recommended as it is made from cow’s milk which has three times more protein than breast milk, making it more difficult for baby to digest. Also, it contains very little iron which is important for the baby’s growth. When choosing formula for babies below 12 months, look out for iron-fortified stage one formula meant for babies in that age group.
