I have a just 4 year old Grandson and my query is what can I do to encourage him to pee standing up....he has been pot trained since 2.25 years and totally dry at night since 2.75.... I know it doesn't really matter yet about standing up to pee but it would make my life a little easier when I take him out which is quite regular. He is in a household with just his Mum and two baby sisters and has no regular male contacts... All advice would be appreciated.
