I dont think you can put it down to just one thing.

There are some teenagers out there who I'm sure think having a baby will be easy, the child will stay cute and little forever. Its also the "love" thing to an extent as well. I think there is many girls out there who maybe do not get the care and attention that they need from their families. As a result, they want a baby who will depend on them, a baby who will need them, and a baby who will love them back. If you get what I mean.

Then there are the people who are taking precautions, using condoms, the pill etc and it does genuinely fail to work and they fall pregnant.

I also think there is a lack of information out there regarding the different types of contraception etc, the facts and the figures regarding each one.this is something I'd like to see improved so each individual can choose the one that best suits there needs.
