I can relate here. I have son, who is now 3.5 years old. I haven't had the time or energy to produce any "finished work" since he's been born, and that marks a lull after 25 years of steady output. I don't feel sad or disappointed about this in the slightest. As my wife likes to say, "it's the season we're in." That said, I do really enjoy chaotic jam sessions with my son, as he's very interested in banging on his little drum set, so in some ways, it's just a new beginning. There's no better investment than time with our children.
