So this morning I had been asleep for what seemed an eyeblink, after coaxing Callum to go back to sleep (he'd woken at 5:30 with the birds and started playfully rolling around the bed), when I was abruptly jolted awake by a few firm pushes to my bottom (did I mention my fractured tailbone?) and a bell-like voice saying, "Mama! Wake up! I need to do a wee-wee!"
I couldn't help it -- I started whimpering.
