... can I just say - why is it if my wife is at home watching her favourite programme my toddler will happily play with his toys and be quiet BUT when I want to watch rugby or anything else he is a complete terror and I spend the whole time up and down like a yo yo!!!!! Any tips ?

I think the key here is go to the pub to watch the rugby

I sat down with my little boy from an early age and watched Rugby with him.
It took a little bit of fast talking when my wife found me letting him watch telly when we had agreed that he shouldn't.
I managed to get round that by saying that Rugby was a cultural thing and it will hopefully prevent him being into football.
Anyway, back to the rugby thing.
I sat there with him and explained what was going on so that he was involved. He obviously didn't understand but he had my attention so was happy.
Now at the grand old age of two years and three months he asks to watch rugby and gets upset when we go out and can't take his "bee ball" with him.
So sit him down, talk to him about the rugby and god willing you'll have Martin Johnson as opposed to some softy footballer who cries every time the wind blows too hard.

I think that is pure genius

I do the same with my boys. Working on the trip to the cabbage patch at Twickenham but baby steps as they say. Keep up the good work Magnus.

Sounds like an awesome idea to share your interests with your little one, it'll give you something in common that you can keep a strong bond through over the years... and its a great excuse to watch the rugby and go to games too!
