Every time I see infants left to the bottle, for all silly reasons (parents busy in window shopping, went for movie, for party etc), it is extremely painful sight. 
🙁
Breast-fed is not just about nutrition but vital immune memories!
And there are some anxious parents who strive physical growth for their kids, on prescription of doctor, start feeding formula.
To Anxious parents who feed formula powders to kids :
रानी लक्ष्मी बाई, महाराणा प्रताप, भगत सिंह, सुभाष चन्द्र बोस, गुरु गोबिंद सिंह जी आदि महावीरों ने कौन सा बेबी पाउडर पीया था?
Stop torturing your kid’s digestion track by artificial nonsense processed food!
Educate parents around you!

Infants receiving different diets after birth develop distinct immune systems
While the researchers expected different diets would promote different intestinal bacteria (microbiota), they were surprised at how dramatically these microbes shaped immunologic development. Specifically, breast-fed macaques had more “memory” T cells and T helper 17 (TH17) cells, which are known to fight salmonella and other pathogens.
These differences persisted for months after the macaques had been weaned and placed on identical diets, indicating that variations in early diet may have long-lasting effects.
“We saw two different immune systems develop: one in animals fed mother’s milk and another in those fed formula,” said Dennis Hartigan-O’Connor, a CNPRC scientist in the Infectious Diseases Unit and Reproductive Sciences and Regenerative Medicine Unit, and an assistant professor in the Department of Medical Microbiology and Immunology at UC Davis.
“But what’s most startling is the durability of these differences. Infant microbes could leave a long-lasting imprint on immune function,” he said.
