They're just two and three respectively, but sometimes it feels as though there's nothing The G and The B don't understand.
I'm not saying they're geniuses, but at times it seems there's no limit to their knowledge.
It's our job, as parents, to teach them about the world, yet with some of the stuff they come out with, you might be forgiven for thinking that they know it already.
It isn't the case, of course.
If ignorance is bliss, it's good to remember that there's a huge amount still to be imparted, the lessons set to stretch over many, many years.
Take The B, for example.
Taking a walk near the beach the other day, he found a large feather lying on the pavement.
He picked it up, studied it and thought for a moment.
"I'm going to take this home and plant it in the garden," he said.
"Then it'll grow into a new seagull."
It's clear that where things come from, a common topic here, is a lesson that has yet to be learnt.
Talking later about where babies come from, The B and The G were reminded that their own lives began 'In Mummy's Tummy'.
Just then, the cat walked past.
The B watched him go and then enquired: "Did he come out of Mummy's Tummy too?"
That there's still a fair bit to teach is clear.
