Secondborn turned five yesterday. For his birthday, he had a cupcake-cake at his school, with Anakin Skywalker facing off against General Grievous. This is basically a matter of his mother pulling things out, since we had nothing whatsoever planned or ready to go.
Then he got home, and found the present (again, left by his mother) on the kitchen table. I think it's safe to say he was pleased.
We may be exhausted, but we can still make a birthday work.
