This is Little Miss Kind. I found her through the Mr. Men blog.
Little Miss Kind was created by Adam Hargreaves. She was made for the 50th anniversary special and was one of 5 characters who fans could vote for to become a permanent part of the series.
Rosie loves way too many things; games, crafting, drawing, painting, design, sewing plushies, planners, music, movies, series. On this blog she shares her creations and other snapshots of stuff she likes.
You might know Rosie from her Twitch channels RosieSoCosy (English) / Rosiewosie (Dutch), her YouTube channels, her planner shop Retro Hugs, or perhaps SimsNetwork, her Sims fansite she started back in 2000.
