i think that if a teenage girl falls pregnant she has a right to make her own decission why do so many go and seek abortion advice? because they know it is confidental.
if parents had to be told probably 8 out of 10 wouldn't go,which i guess would be a good thing if you were anti abortion, but then you are going to have so many girls having unwanted babies because they still won't be able to tell there parents and by the time the mother realises that her daughter is pregnant it will be to late to do anything about it.
i would imagine that most mothers would probably concider taking there daughter for an abortion any way so surley it makes no differance if the mother knows or not.
if the teenager is having sex then i think she would be old enough to sit a make a decission as long as every thing from procedure to after effects(mental) are fully explained.
i guess all we can do as said earlier is make sure we educate our children on sex and how easy it is to fall pregnant, so they aren't nieve and think it won't ever happen to me.
maybe all schools should hand out those interactive dolls that cry need feeding etc then give you a read out weither the doll has been thrown against the wall, ignored ,not fed , then maybe that might make many think twice.
mind you i think that the biggest problem is that many sexually active teenagers are probably to embarrassed to ask the sexual partner to put on a condom. maybe the answer is ,if you think that your daughter may be sexually active suggest they go on the pill.
