i really wouldnt yet if i were you...i know you say you feel you are mature and well travelled etc...and maybe you are somewhat, but the fact still remains...you only left highschool 4 years ago... !
i felt very grown up all through school...maybe compared to others i was, but i know now i wasnt obviously...i am not saying you are not grown up...i am just saying our perception of ourselves changes and isnt what others see ...but i dont think you are as experienced as you think...simply because there hasnt been time for you to be ...
some good points made too -
your career might stall while others at your level bypass you...
once they are here they are here, no going back...
and theres no rush...you both have years ahead of you...
some young parents end up feeling they have missed out on some of their own life by having kids too young too
i am 39 and the thought of having kids still doesnt interest me...i do have a worry that i am pushing my luck a bit now...but still...im not just going to have them because of that...i want it to be for the right reasons...
you are really only just an adult, so i would get yourself sorted with your own lives first for a while, do what you want, be free, and enjoy your youth while you can...
