which month onwards we start non veg for baby ?

A. Some non veg items like certain type of fish or egg yolk can be given around ten months of age. But baby's tummy will be delicate and might find it difficult to digest heavy food like non vegetarian. So it's better to start with all the non vegetarian stuff after the baby completes one year of age. Start them one by one following the two day gap rule between introducing new foods.
