My thinking was wrong when I was pregnant to think that it would be nicer to have 2 boys or 2 girls. For example - how much more fun to have barbie dolls AND army men in the house rather than just one or the other. A beautiful daughter in her prom dress AND a handsome son in his tuxedo. I think most parents worry about their daughters more than their sons, but I wouldn't say one was easier than the other. It depends on the child.
Some boys can be difficult, but so can girls.
It's not so much whether your child is a boy or girl which makes it easier - but the child's personality and temperament. You were both good kids - I was lucky. Seeing you kids in pain - both physically and emotionally. There's nothing worse for a parent than to see their child in pain. All the fun we had at Christmas and the other holidays.
