Are we dumb?

My boyfriend and I are both 18, almost 19. We have both known for the longest time that we want to be parents and feel as if that is one of our purposes in life. Recently we have been talking about it more seriously and considering our options. Right now we both have stable jobs and would be able to financially support a child. I am currently living with my parents and he is living with me part time. My parents have always been extremely supportive and honestly I think my mum would be very excited for a grandchild. I am unsure what I am wanting to do for a future job and therefore I am planning to take a year off to work. I just want to know if there is anyone else who have been through this and whether or not we are being completely dumb and immature.
