Also, if anyone is looking for a skilled editor (fiction / nonfiction) or tech writer, Kat's available for short-term or long-term work; she needs to work from home for the next six months. (The kids will both be old enough for school in the fall.) She edited my memoir for me and gave terrific and thorough feedback; I recommend her unto you for your various projects.
But anyway, while it is occasionally quite loud having four children in the house, my kids seem to quite like having constant playmates. Alex (Kat's 4-year-old daughter) tends to follow Kavi around -- right now, the two girls have gone off to the dining room to have their oatmeal breakfast with milk to drink, while they watch My Little Pony: Equestria Girls. The boys have stayed in the kitchen, eating peanut butter and jam sandwiches, drinking water, and watching Angry Birds videos on YouTube. It is not always (or even often) that clearly gender-divided! Kind of funny when it is.
