Every child is unique, with their own challenges. Each will have a mix of masculine and feminine traits, and each will fit into the family in their own unique way.
That said, even though I was (and am) a hardcore tomboy, my daughter has a good deal of feminine traits. My boy is about as masculine as a six-year-old can be...although he can be clingy at points and loves cuddle time.
My boy is a handful; he's loud, excitable, and
extremely active, and pretty much has to be watched closely at all times. He enjoys taunting his sister, even though the two of them are extremely close.
For her part, my daughter actually seems to enjoy screaming when her brother harasses her. It's a game the two of them play, and they frequently laugh when I come in to break it up. At three years old, she can play quietly by herself for hours at a time. She's very cuddly and affectionate, and just all around a sweet, gentle child. She does love to fuss, though; any small bump requires a good fuss and a band-aid afterward.
My boy hardly blinks unless there's blood, and even then, he's likely to use the blood to chase his sister.
So which is easier? I guess if I'm looking for some writing time, my daughter is the easiest...she can sit and play in the floor while I work, content just to be near me. But if I've got running around to do, my son's the easiest--he can keep up, he likes the activity, and if he stubs his toe along the way, I'm not going to have to spend the next half hour calming him and searching frantically for a band-aid.
Sometimes, having them both is easier than just having one. They entertain each other.
Other times, they get into their little game of harass-and-scream, and they can be nigh unbearable.
Of the two of them, my boy takes after me. Looks like me, acts like me. My daughter takes after my husband's side of the family. Both of them want Mommy Mommy Mommy all the time, unless Daddy's willing to play. Then Mommy is chopped liver.
