I don't have a question, but I wanted to say that you're very right to guard your time with your family. For at least the first year of my son's life, I can't count how many times I'd come home from work and I could see a difference in him compared to the day before. Maybe not even something I could quite put my finger on, but I could just tell there was something different about him. They change and learn so quickly that you could miss a lot in only a few days, let alone weeks or months.
My six week old daughter recently started to smile at me. Even knowing it's just mirroring my face, and there's not much in the way of consciousness there, I could have died happy...
