Right or Wrong?

Rayna • TTC #1 for a 2015 baby. Miscarriage in May 2013.

My boyfriend and I have a close friend/family member that cannot conceive and knowing that I can, we want to have a baby for them. We've both talked to a our parents about this and they believe it's a thoughtful decision and have already told us that they would be behind us the entire time if we decided to do this. We've even went as far as to talk to our friend/family member and they said they would love it and be highly greatful. The thing is I'm only 17 and he's 18. We would really love to give this couple a baby but are we too young to do this?

Thank you for your time.?
