Harry was the favorite kid and he wasn’t even an official part of the family
Because Molly knows exactly how the Dursleys treat him. There’s no way Ron wouldn’t tell her. And Molly Weasley is a Mother. She gets a capital M because she is goddamn phenomenal at what she does. When she hears Harry Potter is on the train to Hogwarts in Book 1, her reaction isn’t to be starstruck. It’s to say “that poor dear had to come here all on his own.” Molly Weasley loves harder than anyone. She loves like it’s her sole reason for being. And when she hears there’s a poor boy who has never known love his whole life… how could she not?
In Year One Molly Weasley knit Harry a Weasley family sweater and made him homemade chocolate so he would have something to open on Christmas DON’T TOUCH ME

"I took a bit of persuasion. They asked me twice. But when they told me everything, including the queen jumping out with a parachute I thought: ‘no one’s even gonna remember I was there, that’s brilliant’. So I thought, yeah… It is one of the best things I have ever, ever done, it was so moving and i’m just so proud to have been a part of it."
