Hi David,
Oh man, do I feel you. My first son is 2 years old now, and it's been a huge adjustment changing the way I create. I used to have several days where I'd just be in my room not communicating with anyone immersed in a piece. That might not sound great to a lot of people but honestly it was something I loved. Those days are gone, and I'm lucky to get 45 minutes of uninterrupted time. Buuuut it's still a small price to pay whenever you look at your little ones doing what little ones do. Beautiful paintings, looks like you're making it work. :)
