I agree that people shouldn't try to play God and that you're blessed to be able to conceive a healthy baby.
When I was like 13, I use to want a boy and two girls in that exact order. My friend convinced me that I should have boys before girls so they wouldn't be "soft" and have at least 2 girls so they won't be tomboys and their big brother could protect them. I know that sounds stupid, but I was only 13.
IF I ever have children, I'd count it all joy no matter the sex. Life is precious. But after seeing countless acquaintences have kids and volunteering with bratty kids, it would be a miracle if I purposely try to have a baby anytime in the next 10-15 years. I'll stick with dogs. They're easier.
