Happy to help with this one! Some of their plates come from Target. But I’m guessing you’re referring to the pink tray, as I get A LOT of requests on this one.  It is by Sugarbooger. Our set actually came from a friend for Addie’s second birthday. It was purchased from one of my favorite stores in Orange County, CC Roo on 17th Street in Costa Mesa.  But I just found it online as well (and some cute other patterns too!) Check out o.r.e. This link should take you directly to the childrens’ plate sets!  Good Luck!
