Sasha, you are not the only one with these thoughts!!! i just found out today, baby no 4 is a girl, i had joked to df befor, that our boys have days were they just fight and fight, (like his teen brothers) if we have another girl, they both better not turn out like his sisters!! (worse then the boys!) i was never close to my sister, im still not, i guess being 11 years older makes it hard!
every parent wants there kids to get along and be great friends! be nice if they poped out with guidlines!!!!

best of luck to raising happy kids that get along!
