When we were at our son’s two week old checkup, our doctor must have noticed the weary, anxious look in our eyes and told us, “Don’t worry. Once he gets to be about six weeks old he’ll start smiling and interacting with you and it will be a lot more fun.”

I looked at her and thought, But I like him now. I was tired, but I didn’t want him to change. To me, there was not a single thing wrong with him staying as he was. My love was stronger than the pain in my body, the circles under my eyes.

I was new-parent weary, but my love for him was so big I couldn’t imagine how it could get any bigger.

Before I became pregnant, I actually couldn’t imagine myself with a newborn. I thought I would be better with an older baby, one with large curious eyes and soft, squishy chub. I didn’t know what to do with squinty-eyed newborns, who seemed so fragile and apparently cried or slept all the time. But as soon as my son was born and lying on my stomach, I saw his beautiful face and all I could think was how perfect he was.

Watching a child grow is like watching a flower bloom. My son started out a tight little bud, and as he gets older he blooms out, revealing the beauty inside. As he blooms, my love stays as strong as that first day, but my appreciation for his loveliness grows.

I have a friend whose baby was born just a couple months before my son. We shared our excitement and fears about pregnancy, and then parenting once our babies were born. When our sons were just a few months old we talked about how we didn’t want them to get bigger, how we loved them so much as they were and we were weepy when they outgrew their clothes. But we discovered as our babies grew how exciting each new milestone was. How just when we snuggled our babies close and smelled their heads and thought, “Don’t grow,” they surprised us with some fascinating new development and we couldn’t tear our eyes away. Suddenly, we were cheering them, saying “Go on! Do it again!”

Nothing can prepare you for the ordinary miracle of your baby doing something for the first time. I’ve thought about why that is. All healthy babies follow the same general pattern of development. Why should it be more exciting when mine learns to roll over or crawl or walk? But as his parent, I’ve been with my son from the beginning. I’ve been on a journey getting to know him since I first saw his heart beating on the ultrasound. As his parent, my every daily activity is done with consideration for this little being that I am responsible to grow. So when suddenly he does something that he’s never done before, it feels like my world is expanding right along with his.

When my son took his first steps, even though I had been expecting it for months, I felt as though something impossible was happening. I couldn’t have been more surprised if he was spoon bending, Matrix style. It was breathtaking that he should stay upright on his own, even for a brief moment. I cried, seeing him walk. Because my baby is almost not a baby anymore. But also because I got him this far. And also because I’m so excited to see all the things he is going to do next.

So if you asked me every month of my son’s life what my favorite age was, I would always say “this one.” It’s true now, as he practices walking while holding a large ball, or uses rudimentary sign language to ask for “help”, or holds his dog’s paw while he watches Daniel Tiger’s Neighborhood. I hope that no matter how difficult things get, whether I’m losing sleep because of toddler nightmares or teenage escapades, my love continues to be stronger and my appreciation richer.  I hope I can always say, “This is my favorite age,” because he is my favorite boy and I wouldn’t have him any other way.
