Things only dads do: the silent car seat recline
You know that moment when your kid finally falls asleep in the car and you're trying SO hard not to make any noise? I literally drove 45 minutes the long way home yesterday to keep my son asleep. Took the quiet back roads, avoided potholes, didn't touch the radio. My wife asked why the trip took so long and I just pointed at him knocked out in the back. She understood. We sat in the garage for 20 more minutes.
Oh man the car seat recline freeze. You don't even breathe wrong or adjust the radio volume. One single wrong move and the whole evening goes sideways. I feel this on a spiritual level.
