I love yellow and grey too. On the yellow wall, the shelves are white, and I found really cute plastic bins at dollarama so I stocked up on white and grey ones. If I ever get it done, I'll try to take some pictures. I guess I'm more excited about this than I realized!
And on the original topic, the little grumpy child wasn't as bad as he could have been! I've seen him worse. Lol
