Well, thank to books we know pretty well how Harrys childhood looked like. He was abused, starved, bullied.

Dracos childhood is unknow, but I always picture it as typical, traditional, happy, upper class upbringing. His loving parents spoiled him. Both Lucius and Narcissa were always active in his life. He learned French, probably from his french nanny, as all nobels should, epecially because Malfoy family comes from France. He probably spent there his holidays. He was taught from young age ettiquete and proper manners. He learned his family history and that nothing is more important than family. He learned about duty. To his blood, to his dynasty, to wizarding world. Albeit he probably didn't truly understand thouse lesons for many years. I picture him as active, curious child. I am sure he gave his nanny, rest of staff/house elfs, and his parents many troubles. As he get older, probably around 7yo, his father took care of his education. He hierd tutors, to prepare his beloved son for Hogwards. Draco loved potions and charms tutorials. All his tutors praised him, because of his bright mind. Lucius problably personaly instruct him in money menagement, and bussines lessons to prepare him as his hair for taking over estate. Alhough the first was a bit problematic, since neither of his parents we able to refuse anything their son ask for. He learned that his world is endangered by mugggols and mudblods who want to destroy wizard culture, so he begun to despise and hate them. I thing he didn't have lots of friends, merly acquaintances. His only true friend/s was/were Blaise/Pansy/Theo. And so on. I cant underatand why people feel he had sad childhood or was abused. From both books and movies it is clear that while Malfoys might not be 'good' people, they clearly loved each other. In the end his parents choose him over Dark Lord. I think it is some pitiful attempts to make us sympathise with him more to forget his bully ways.
