Hi. I got married at 20, and said we would wait till 24/5 before having a baby. I fell pregnant on our honeymoon! We now have a beatiful 13 week old girl. We wouldn't change things if we could. We are soo happy that she came along and are absolutely loving every minute of it! I'm 21 now and we are trying for no2. My parents are supportive of that, my husbands parents are no longer a part of our lives. They still aren't supportive of no 1, so theres no way we'll tell them we are trying again.
I always though you should wait till you are financially stable, but i don't think we would ever have kids if we did that. By time we own our own home i'd be too old for kids. I think if both partners want kids and you have good support from family/friends, then go for it. Raising a child is the best job you can ever have!
Good Luck to all of you who are trying or already have kids!
