I remember it well! finn used to go out for ages and then come back inside so he could wee on the paper, having clearly been keeping his legs crossed till he was back inside!

some people move the paper closer and closer to the door, even leaving the door into the garden open and then putting it on the step outside, but it's a bit chilly for that at the moment!

I would move the soiled paper into the garden and show it to him out there and of course make big fuss of him when he does do it outside...
