Is the practice of "tahnik" for an infant exclusive to the Messenger of Allah, may Allah bless him and grant him peace?

The Prophet's tahnik (rubbing the palate of a newborn with chewed date) upon children is a followable Sunnah (definition). It involves a person chewing a date and then rubbing it on the newborn's palate, opening the baby's mouth so that some of it descends into their stomach. If dates are not available, any sweet substance can be used. The proof for tahnik is the hadith (definition) of Anas (may Allah be pleased with him), narrated by Muslim. Most jurists have deemed tahnik to be recommended.
