I'm so jealous of the preggo's and TTCers because I'm dead broody, but we won't possibly join their ranks for another few months... so I'll obsess about this instead! I know too much about the "tricks" to not be conscious of how to skew the odds towards having a boy or a girl, next time. The existing children would be 4.5yo+ boy, and 2.5yo+ girl.
Is it better to have a boy, because my middle child will be the only girl, or better to have a girl because they're less boisterious & wear cuter clothes? Are girls or boys more expensive in the long run? Though we're quite a sporty family, too. A baby brother boy would be less interested in same toys as his near-age sister and far-age brother. But then, 2 boys room-sharing with a 4.5 yo gap sounds less practical than 2 girls sharing with 2.5y gap. How would you decide?
