When do you start to buy new born stuff?

I was kiasu, and started the moment I found out at 15 weeks! I had a strong hunch that it was going to be a boy (but if I'm wrong, my would have been girl will have to suck it up lol) so I went mad each time I walked past Cotton On Kids, H&M kids and Isetan. I bought most of the baby essentials during the babyfair at Expo. Baby bottles, stroller, carrier, sterillizer and more. It was so much cheaper to buy there!
