There's a fanfic called 'Motherly Figures in Harry's Life'. It shows how different characters, like Luna, can also have a motherly influence on Harry. Luna gives him advice and a kind of calm support that he really needs. And then there's 'Harry's Motherly Guardian'. This one has an original character who steps in as a motherly figure for Harry, protecting him from the dark forces in a unique way.
One great motherly Harry Potter fanfic is 'The Motherly Love of Hermione'. In this fic, Hermione takes on a motherly role towards Harry. She looks out for him in ways that are really heart - warming, like making sure he eats well during the tough times at Hogwarts. Another is 'A Mother's Care by Molly Weasley'. It focuses on Molly treating Harry as one of her own sons, with lots of hugs and home - cooked meals.
I really like 'Motherly Magic'. In this fanfic, the magic itself seems to have a motherly quality when it comes to Harry. It heals his emotional wounds and guides him in a way that's like a mother would. The descriptions of how the magic interacts with Harry are really beautifully written, making it a very interesting read for Harry Potter fans.
