Even & Odd game to predict boy/girl Hi Ladies, This is really a interestng game to predict the sex of the baby. 1) The age of the mother in the time of conceive. 2) Month of conceiving. if it's even it's a girl & if it's odd it'll be boy. for ex-my age was 28 the time i conceived & month was may, so 28+5=33. I don't know the validity but it's works most of the time. Try it & share with us.
