My son was born a week and a half ago. My feet haven’t quite touched the ground yet, but I’m back at work and still trying to take stock of how much things have changed.

Shortly before Leo was born, I asked readers for a bit of advice. The feedback was good and profound. A reader named Cathy wrote, “There's a good line from a Steve Martin movie...there's no way to be a perfect parent but there are a million ways to be a good one.” I liked that. A personal friend told me to remember “the days are long, but the years are short.” Very, very true.

The two pieces of advice I have are not nearly as profound, but I hope they help more than one dad-to-be out there. Here it goes:

First, learn to swaddle the baby. You’ll mostly need this skill on night two, when the baby realizes his change of environment is permanent. He’ll feel a little more secure if he’s in that snug environment. It’s likely the nurses and other hospital staff will be able to help you with this, but you’ll be proud to be able to do it yourself.

Second, assuming you’re going to be spending a night or two in the hospital with your wife, do yourself one favor. Bring an air mattress. The sofa bed you’ll be sleeping on is not fit for human backs. True, you’ll be so tired those first two nights that you will manage to sleep anyway. And your discomfort is nothing compared with what your roommate will have just endured, but still.

I hope you weren’t expecting anything more profound. I don’t have it, yet. I can tell you that I feel so much closer to my wife. I feel closer to my stepdaughters, too. I don’t share a blood relationship with Kay and Pax, but my son is their brother, and that cements us as a family. From the day I married their mom, I promised Kay and Pax that I would love them as my very own. But how could I have known what that meant? I didn’t have a child of my own until a week and a half ago.

Now I have three, because I understand now what that promise meant.

Everyone is different. I can’t tell you that you will become closer to the members of your household. I can’t tell you that your relationship with your wife will become deeper and more meaningful. That’s not advice. It’s been my privilege to experience, and it is my wish for you.

My advice? Learn to swaddle. And bring an air mattress. Your back will thank you.
