He is old enough to wear pyjamas, but not quite old enough to ensure that the yoghurt avoid his face on its way to his mouth. He is also, as you can tell, already a veteran poser for photographs. I guess that is what comes of being born in the age he is. And being a first child and first grandchild.
I hope he grows up strong. I fear there is plenty of clearing up to do in the world. And will no doubt be more by the time he is twenty.
