None of my business?????
its not iilegal to give medised to a child under 2 but its not "recommended" i think this was due to people doing exactly what your neighbour is doing. can you not research the side effects and bring the conversation up again and tell her what they are? you cant tell someone whether or not to smoke, swear etc in front of their children however if they are pissed then that is unlawful drunk in charge of a minor. personally id mind my own business and keep myself to myself UNLESS i knew for a fact that the children are coming to harm. then id tell the appropriate authorities but id tell her first.
