I tinkered around with sourdough quite a bit before my daughter was born. I loved experimenting with my excess - sourdough pancakes, even chocolate cake (which was quite good). Then I gave birth and I gave up on all that. Got to get started again.

2 and 4. Finally ages that are requiring a little less, so I can do more in other areas.
