do you want someone to try putting you off?
here goes (i'm gonna be brutal)
children suck the life from you. literally. you are decreasing your life expectancy with each one you have. (think increased weight, extra work for your heart etc)
they drain your bank account without even caring
they ruin your house (probably your biggest financial investment).
they damage your sex life
they change, irrevocably, your relationship with your dp
they are loud, messy, ungrateful and selfish
they just get worse as they get older
there is no guarantee that they will love you back, or even like you much
there is NO logical, good reason for having a child. the only reason to have one is a hormonally driven requirement for the species to continue - to give in to it is just to allow your 'animal' side to take over, rather than your civilised human self.
you will grow out of this phase when you get to the menopause
have i done my job?
(would love another, but can't, so i tell myself this as cold comfort)
