DS will be 6 in 3 months time
for the past 2 months my mother has insisted on referring to him as 6 and laughs scathingly at me when I say he's 5 (or 5 and a half .. I can't bring myself to say 5 and 3/4)
DD is 2 and a half .. exactly .. but to my sisters she's almost 3
why do they do that .. and are my family the only ones who do?
