Welcome to the club. We take donations for hospitalized members.
I suggest you get a nice cover to go with it, just in case she finds this thread; so she doesn't break the iPad when she hits you with it.
I know the feeling. I'm the oldest kid (24) in the family, and when I bought my first iPod several years ago, I opened the gates to heaven - literally. Our family, consisting of dad, mum, me and my little brother (20) together owns 3 iPod Touch, 3 iPhone 3G, 3 iPhone 3GS, 3 iPhone 4, one MBP 17 (late 2011), 2 iPad 2 64GB 3G, one MBP 13 (late 2011) AND an airport express WiFi switch. All this bought during several years, ofc.
