Although many people seem to want a daughter, I do know a few people who wanted a boy, and one couple who couldn't conceive adopted a boy. In addition, I know many people who love their boys as much as their girls. (And people who do love their boys if they only have boys...) And the case of the woman I knew was an extreme one. She was a spoilt brat as a child anyway, who threw her toys out of the pram when she never got her own way, and as an adult, she was no different.
But even though sons are loved, and many people are (quite rightly) happy with their boys, I don't think anyone can deny that lots of people desire a girl. Not that they don't want a boy at ALL, they just want that one daughter. Even if they have they have 5 kids, and 4 are boys, they just want that one daughter. They won't love their boys any less, but there is a deep desire for a daughter for many women (and some men.)
As has been mentioned on here, whenever there is gender disappointment on threads on here (or on other forums,) or in real life, it's NEVER when it's a girl. People (usually women) are usually pleased if it's a girl. I have seen people cry at yet another boy, but never if it's another girl.
As I said earlier though, some 40+ years back, boys seemed to be preferred to girls, and I know many a woman of 45-50 (and older) now, who can tell a tale of how their mother preferred their brother. Boys were definitely favoured then. For some reason, this past 2 or 3 decades or so, it's turned around, and the desire now, is often for a daughter.
I am not saying either one is better, but it's definitely true that daughters have been more desired for the past quarter century or more.... but most women. Maybe it's because - as I said earlier - they had a mother who favoured their brother(s,) and they wanted to create a special mother-daughter bond that they never had.
As a few people have said, I see some posters here getting arsey because people prefer girls, (and are giving reasons for wanting daughters,) and then in the next breath, they are saying they only wanted boys, and girls are awful, they're hard work, they're glad they didn't have one yada yada...
Disingenuous much?
