I feel sorry for them being so uncomfortable (I've been there, I know), so I sit with them in the evenings (the LaMancha usually comes and lays down beside me), and I pet her and talk to her and watch the sun go down. It's really relaxing (for all of us I think). I even had a cottontail rabbit come within a foot of us a few nights ago.
So, just call me Doula until these girls give birth because I seem to be their favorite person these days, and hopefully I'll get to see their little ones come into this world. That would be really neat.
