The ones that have proved to be true for me are the decrease in hair growth (awesome) and the sweet cravings!
I totally agree with you saying that your daughter knew because my son knew from the very begining that I was having a girl, He kept telling everyone it was a girl and he would fight with you if you told him any different.
I think it depends on the person . I am 26 weeks pregnant with a boy and I crave sweets like crazy, my skin on my face is more irritated then with my daughter and I dont feel beautiful at all. The pregnancy with my daughter wss the complete opposite. The old wives tale that I do believe is that if you are carrying a boy girls are more prone to want to be bothered with you if your carring a girl boys are more prone to want to be bothered. Opposites attract...my daughter always wants to be near me and rub my belly and hug and kiss me a lot more now, then before I was pregnant. She knew I was having a boy before I did. My nephew can't stand me now, when he sees me he runs, no hugs, or kisses for his aunti....he wasnt like that before the pregnancy. Kids can sense certain things
The girl steals your beauty one was true for me. Not sure if its a wives tale but my leg hair has stopped growing (with my son it grew like crazy) and the craving sweets with a girl has been true too lol
