Hermione nodded her head, "All children, even children from wizard families, start experiencing short bursts of magic. Initially they can’t control it because they don’t know what it is or where it comes from. But as you grow older, you get familiarized with own magic. For me, I can see my magic in mind,’ she mumbled, and then blushed at babbling something so personal out. "Anyways, but it takes time. Neville started showing magic a lot later which is why it used to be so hard for him to control it the way he wanted. May be that’s why he is so accident prone. And as for Harry, he couldn’t control it even after he started coming to Hogwarts. He even blew up his Aunt Marge before our third year.’
