My friend who's daughter goes to jays pre school is always complaining about her girl. Shes whiny, demanding, bossy, has so many tantrums etc. She wishes her second child had been another boy like her first. Same with a grandparent who's grand daughter is at the pre school, she has 2 grandsons and says they were so much easier than the girl.
I couldnt have asked for a better personality in Jay
Each child is different, they all have different personalities. I think it depends on your parenting too. So I wouldnt assume a second boy will be like your first. There's every chance they will be total opposites.
