actually, some 14 year olds will have kids young, some won't.
if they all have learnt something about parenting, the care and responsibility required, the relevant health issues, financial needs, emotional and physical needs, the demands trauma and generally life changing and life-swamping (style cramping) impact that a child can bring, then this is a good thing. maybe it might make them more aware of the commitment and take better precautions. erratic parenting can cause ennrmous stress to a young child which can lead to potentially fatal health problems later in life.
so, if the option is we dont consider this and we have loads of youngsters unwittingly brining sprogs into the world that they can't coipe with and get ill and we end up paying for subsidiary care - or that we educate them a little so that they are more informed, and hopefully more careful, then i would opt for the latter.
