Focus on your family. There is absolutely no need whatsoever to go to a conference in person to hear people talk about bitcoin and Nostr. Those things are talked about here already, all day, every day.
The fact that you have a kid is a blessing that wins over whatever meme is trending here or what the bitcoin price is at whatever time.
This is by no means medical advice. This is just me tellin you:
Spend time with your kid. As much time as you can, every day.
You are already ahead of the curve just by being able to have a family.
