My son was just a baby when I divorced my husband. And, even before that, most of his time was spent around me and his sister who is 10 years older than him.
Trust me, at that age, I truly believe that kids are "generic".
My son played with my daughter's Barbies, he loved wearing my shoes, and, there were plenty of days he'd throw a fit if he couldn't have a hair pretty in his hair because Mommy and Sissy had one. I have pictures of my son with barrettes and rubber bands in his hair. I used to sit on the edge of my spa bathtub and he would brush and "curl" my hair for hours (with the curling iron unplugged). He was obsessed with toy kitchen sets and toy vaccuum cleaners. He had his own little broom and apron. When we went shopping, he would tug at the bottom of something on the rack and say, "Oh, this is SO cute!" If he was in the cart and could reach, he would hold skirts and feminine tops up to himself.
He actually had pretty good taste in clothes.
My son will be 17 on the 28th of this month. He is 6'2", weighs 200 pounds and is very much a masculine young man in every sense of the word. There is nothing at all girly about him. That said, he knows how to cook, clean, sew. A few years ago, a male coworker had a fit when he heard that I was buying my son his own sewing machine. I said, "What is he supposed to do when he grows up? Make his Mommy sew everything for him?" He answered, "NO! He's supposed to get married and make his WIFE do it!"
Ummmmm, no.
My son will make a great husband one day. He is an amazing uncle to my grandson and wants children of his own.
My nephew went through a phase where his favorite color was pink. He wanted EVERYTHING pink. He threw a fit over wanting pink Power Ranger slippers. My sister suggested the green ones or the blue ones. Nothing doing. He wanted the pink ones.
He outgrew it. He hunts and fishes and always has beautiful girlfriends.
I really think it's just a phase. Children this young don't understand sexuality and I know first hand that my son and nephew don't have any gender identity issues because they were interested in "girly" things at a very young age. Your son will feel uncomfortable in his skin if you make him feel uncomfortable about it. This is my opinion.
My husband, who was a "macho" control freak didn't even have any problems with our son having a hair pretty in his hair or whatever. He was over it well before kindergarten
I think it's too soon to worry or make an issue of it.
Again....this is just my personal opinion.
