I'm getting back into the habit of monthly shoots, Louise. I used to do photo shoots frequently - but not regularly - a few years back, and after losing three pigs over the past year, I thought "Well since I don't take random photos much any more, I would like to know I have a picture of each pig from each month of the year". I've found I'd rather have lots of pics of the pigs (though not lots the same) and be stuck for which one to choose, rather than just have one or two pics which show the character. I only have one photo of Charlie and Lottie that I am really happy with, and I don't want to be in that situation again where I wished I had more pictures, better pictures.
I suspect Willa is going to be the same as Tuppy though; I will have too many gorgeous pics to choose from. She is so like Tuppy in the way she poses and behaves, just without the attitude.
