steralising

who else is still steralising? im not ...stopped 3 weeks or so ago baby fine ....he 6 months old ....i dont see point in steralising when they pick up stuff off floor ...we dont steralise their toys ,clothes and toys others have played with etc .... anybody else agree ...i even stopped steralising when my oldest was 7 months roughly ...i know people who have never steralised and their kids have never been ill ....
