Zam zam water survival

Salamu alaikum. I am a sister who plans to move to Saudi Arabia and live there permanently inshaAllah as they now issue permanent resident visa to foreigners if they pay a lot of money. My questions is for those who know Madinatul Munawwarah as I have never been there. Is it possible for me to get at least 10 liters of zam zam water daily from Masjidun Nabawiyy if I live in Madinah? Will I be able to get the zam zam water if I go to the mosque by car? What about during seasons of Hajj and umrah? Will I be able to get it despite the crowds of people that will be there? What about if I were to live in Makkah not Madinah? Will I be able to get the zam zam daily even during crowds seasons of hajj and umrah? Another question I have is regarding the hadith that says zam zam water can substitute food and about the historical story which says that the people of Makkah regard zam zam water as shabba'ah and that they used to give it as food to their children. I am a sister who doesn't really like to breastfeed her newborn children if I happen to give birth to any. Can I use zam zam water with additives like honey and other natural sweeteners as a sole source of nourishment for my newborn babies? Will zam zam water satisfy them and make them grow and be healthy?
