Just navigated my first doctor visit and actually knew what was happening
This might sound dumb but I used to just stand there while my wife talked to the pediatrician. Today at the 2-month checkup I actually asked questions about the vaccine schedule and knew what percentile our daughter was in without being told. Felt like I leveled up somehow lol. The nurse even asked my opinion on something and I had an actual answer. Small wins but feeling proud of myself for showing up mentally instead of just physically being there.
The nurse noticing you were engaged is probably because a lot of dads just stand there silently. You asking questions and being present probably stood out. That's solid.
