I have a new sweatshirt. It is grey and purple, fleecy and soft. And it is the perfect weight for winter we have been having. Not only was this sweatshirt on sale, I had a coupon and an extra discount for recently celebrating my birthday. All told, I believe the store paid me to take the sweatshirt off their hands.

Because it was a recent purchase, I wore it for the first time this weekend. It immediately got my daughter’s attention. “I like that shirt, Mom,” she told me, running her hand up my arm. “It’s so soft!”

“Thanks,” I replied. “It’s the same brand as the one you have, but it’s a different style.”

“I really like this one.” She paused, and I could see the wheels turning in her head. “Did you get me one, too?” she asked, smiling and batting her eyes for effect.

Of course, I thought. Because I always buy you things when I buy things… just to make it fair. But to her, I said, “Um, no. I didn’t think ‘matching your mother’ was on your fifteen-year-old bucket list.” I winked.

She shrugged her shoulders. “That’s okay. I’ll bet I can wear that one.” She turned, her hair flipping, and skipped up the stairs. And I realized that for the first time, she probably could wear this sweatshirt—my sweatshirt—and more importantly, that this is a major milestone for this kid.

Almost exactly a year ago, this child, who’s always run a little on the small side, was being tested to make sure that she wasn’t deficient in anything necessary for “normal” development. Even though she had always been off the bottom of the growth chart, the doctor just wanted to be sure. The blood tests and x-rays revealed that all is fine, but her bone age is two years lower than her chronological age.

Since that time, she has gained ten pounds and grown several inches. She eats non-stop, and she is always hungry. (I don’t know why no one ever talks about how much teenage girls can eat. If you get enough skinny dancers in your house, you may as well be feeding an army of teenage boys….)

While my daughter is still small for her age, she’s catching up. It wasn’t until she asked about my sweatshirt that I recognized my shirt is only one size larger than her own. She could easily wear it, and it would only be a little big. So for now, I’ll keep it in a safe (and hidden) place. But soon, she’ll be wearing it. I can share. And after all, I’m kind of flattered that my clothes fit her teenage sense of style.
