Every so often when your kids are growing up, one of them will do or say something which reminds you that they won't be so young and "innocent" for long.
I had one such moment last night when I rushed home with some cut price sleeping attire for him and her.
Charlotte was delighted with her Shopkins nightie, which pleased me greatly.
But Jamie was a touch more standoffish about his Batman pyjamas, complete with Bat Cape.
He wasn't rude, to be fair. He just seemed a little underwhelmed.
"Do you not like them?" I whimpered.
"Well, yeah," he replied, looking a touch awkward.
"Do you not like the cape?" I ploughed on, with a dollop of desperation.
"Well, the thing is Daddy," he said, "it's not really me."
"Why not?!" I pleaded to know.
"Because I'm almost eight."
And I'm old enough to be Robin's dad.
