Teething is a natural or physiological process that starts at 6-8months and ends at 2-3 years. Almost all babies experience teething though emergence is earlier in females and tend to occur in pairs.

In medicine, there are standard treatment guidelines that provide information and treatment protocols for diseases. As a general rule of thumb, essential newborn care involves clean environment for delivery, clean cord cut, clean cord tie, clean cord care, vitamin k, care of the eye, provide warmth, early initiation of breastfeeding, exclusive breastfeeding, rooming in/bonding, immunization. There's no place for antibiotics treatment as routine care. If there's neonatal sepsis; the baby will be treated accordingly. While we know that the level of health care delivery and services vary; there still remains a standard guideline. If your healthcare provider does outside the norm, doesn't make it right or that someone is providing wrong info. What makes you think your info is the right thing. AGAIN in medicine, we individualize patients. Everyone's signs and symptoms may vary. Let's stop generalizing. Your healthcare provider should justify his/her actions. One cap doesn't fit all!
