I got an hour in at the garden today. It seems to be the limit of the kids together. I don't know how they can antagonize each other when one of them is a year old and under 15 lbs, but she gives as good as she gets. Ronan, of course, is incapable of removing himself from the situation and prefers to be a martyr.
I managed to locate my shiso (purple perilla) volunteers and cleared space around them.
And I think I have
explodingcat's blessing to go back out to the garden and work some more sans children. RIght now. Rather, as soon as I disconnect from the magical milking machine.
