May the best team win! :P
I don't have a strong preference either way. Three feels like a good number, four feels like too many for me personally. If we have a boy next, I can see us stopping at two or going for a tie-breaker. If we have another girl next, I'd probably want to try for a boy (and then be divinely happy anyway if we ended up with 3 girls!).
Of course we're both onlys, so the sibling dynamics thing is a whole new ballgame. ;)
I don't have any strong feelings either way. We're set on having two now, but I wouldn't not have a third just cause of uneven numbers. I don't think it makes a big difference either way.
For some reason I am drawn to odd numbers. I would rather have 7 or 9 kids instead of 8. I think it just seems too neat to me.
