How can I display random items from a collection on my homepage?

Hi all, I have Shopify store www.stuffs4newborns.com. On the homepage, I have a section for ’

BABY CLOTHING NEW ARRIVALS’ which is displaying 10 items in 2 rows. I want this section to display random items from the same collection, every time when homepage loaded. I would appreciate if anyone could help me to achieve this. Many Thanks
