When should you start disciplining a baby - is 10mths too young? My DS has started doing things which he shouldn't (e.g. pulling hair, scratching/pinching faces, throwing food on floor on purpose, pulling electric cable etc etc). Not sure whether to just ignore his behaviour and distract him/move him or to say NO/shout/point finger?
So far saying "NO" results in him laughing and doing it again, thinking it's a game!
