Kissing a baby may seem loving, but it can expose their developing immune system to millions of bacteria and viruses they aren’t yet ready to fight. Infants are especially vulnerable because their immune defenses are still forming, making common adult microbes potentially harmful. According to The Conversation, even everyday bacteria like E. coli can be transferred through close contact such as kissing. This is why health experts urge caregivers to be mindful of hygiene and avoid kissing babies when feeling unwell. Protecting infants from unnecessary exposure helps support their healthy growth and early immune development. #fblifestyle
