What oral antibiotics can be safely used in newborn babies, and at what doses ?

Here is a list of oral antibiotics that can be used in newborn babies.
This is something that even I as a pediatrician get confused about, hence hopefully this will be a ready reckoner for the child specialist.

Please remember, we DO NOT WANT to give antibiotics to small babies, and so do NOT self medicate with these medicines.
