Did the Sharia recommend any foods for infants and young children other than breast milk?

Types of food and drink are from the customary practices, and the default ruling concerning them is permissibility, except for what has been forbidden by evidence. A person may eat and wear what they wish, as long as it does not involve extravagance, wastefulness, or arrogance, as Ibn Abbas said: "Eat what you wish and wear what you wish, so long as two things do not befall you: extravagance or pride."

No sacred texts have been transmitted that encourage a specific food for children, and the Companions were not people of luxury; rather, their staple food was dates. Aisha mentioned a story of a poor woman feeding her two daughters dates, whereupon the Messenger of Allah (peace be upon him) said: "Indeed, Allah has made Paradise obligatory for her because of it, or has freed her from the Fire because of it."

Furthermore, the Sunnah established the practice of tahneek (rubbing the palate) with dates for a newborn. There was no specific food for children in the Prophetic era; rather, they ate what their families ate, while infants were nourished by their mother's milk.
