OT- HELP!!!

My 3 yr old scribbled on our new leather sectional with a pen. Not too bad. What can I use to get it off? Maybe bad thing but I know hairspray brings pen marks off of clothes so I sprayed it first & wiped it off. Now it's really light but still there. Please Help. Baby doesn't understand that mom & dads first brand new couch & it was bought just for her (because of allergies) & cost nearly $2000.00!!! I told her no more writing while 'on the couch'. Of course she's too young to understand $ & the other 2 daughters thinks it grows on the $ tree out back lol! Any advice welcome!!!
