Nutkin returns

This is the female squirrel that eats peanuts out of my hand, whom I've named Nutkin (after the Beatrix Potter character). She was a regular over the winter and into the spring, but then less so as summer began. That is until she was nursing her first litter. Then she came to the door multiple times a day for sustenance! That tapered off, but here she is again. I'm thinking she is pregnant with her second litter.
