There are the usual things to say.
As Boy as ever.
All are true, but also.
I can't help wonder.
How will I parent a young man who is all of these things?
And so I went to bed and the answer came at four in the morning,
when he crawled next to me, distressed by an earache.
In a still, small, boy voice, he said "Mum, I'm alone in my room"
Five, fifteen and beyond, I will be close when he calls for me.
Happy birthday Zeb-boy!
