By what age realistically do us ladies need to have completed our families?
I am 36 and will be 37 in a few months we have always wanted 4 children i currently have 3 and we recently bought a new home suitable for 4 i realise the sooner we have the 4th the better as fertility will be downwards here on but right now wouldn't be ideal i guess I'm trying to gauge by what age i should aim to have completed our family by?
