This is very sweet in many ways. On a more practical level, it has meant that Mummy and Daddy didn't get much sleep last night. And then today, Mummy has hardly had a minute's peace.
After a day out in Otley on Friday with Granny, Grandpa Derek and Mummy whilst Daddy worked (OK, he was at a works Christmas lunch), Jamie then spent all day Saturday with Granny again whilst Grandpa Derek and Daddy went to Manchester to watch City v Everton (what?!)
And yesterday, Granny, Grandpa Derek, Mummy and Daddy (yes, really) took him shopping and then on to the German market in Leeds.
Unfortunately Granny wasn't able to take Jamie on the hobby horses as originally planned as they were a little too big for him. But he did enjoy watching Mummy and Daddy knock seven bells out of each other on the dodgems.
And after being terrified to begin with, he kind of chilled out to the Oompah band in the marquee where Grandpa Derek and Daddy enjoyed a big pint. And also The Yeadon Stoops bar where they had another (and Jamie had some carrot).
But, sadly, his guests soon had to leave and the grumpiness began.
24 hours on and Jamie still isn't really himself - Grannylove is good, after all - but he is already looking forward to seeing Granny White and Grandpa Derek again next month when he goes back across the Irish Sea to see all his relatives who talk funny.
And before then - guess what? Father Christmas is coming - NOW GO TO SLEEP!
