IMO it depends on the person. Some 17 year olds are mature for they're age and can take care of themselves and a baby. Personally I never was one of those people and have decided that I'd rather wait a couple years, live the single life for a little while, save up money, find a stable job, and then adopt a baby/child. Again, that's just me though. If the 17 year old has thought everything through and has the resources (house, job, etc) to support the baby then ok, if not then they should not have a baby or if they are already pregnant then they have some serious decisions to make. Again, it's just my opinion.
