Gideon has been tired for weeks. Possibly *months*. He's not walked more than about 30m without asking to be picked up.
And then, today, suddenly he's running all over the place, full of energy, and sat in the buggy for a total of 3 minutes when we were out for two weeks a half hours earlier.
And now it's half past ten at night, and he's failed to go to sleep three times, Jane has given up and gone to sleep leaving him downstairs with me (only fair as I got more sleep last night), and he's just asked for me to put on "robot dance" for him so he can leap around the room.
Hopefully this all evens out a bit tomorrow!
