Ahaha actually this is quite normal for the first born children, most parents do all that and when the second child is born, they start to slack off on the whole adult language, reading books etc xD the second and other “newer” siblings are left to play/learn from the eldest kid.
I am the 4th child and I wasn't pushed to learn the piano and the like but, I was taught to read and write and was always told to find something to do if I ever mentioned being bored. Learning from older siblings generally means experimenting earlier than they did. Also, learning how not to get caught ;)
