Oliver's favourite pose

Most often than not when you look at Oliver, this is what you will see. He has been doing this ever since he was a baby and no matter how much we discourage it, his finger always finds its way up his nose. When he is tired this is how he puts himself to sleep. The annoying thing though is with the two middle fingers in his mouth, Oliver makes this really loud slurping sound which can be very annoying when he has found his way into your bed in the middle of the night. I hope he does not take the habit on like one of my sister's who was still sucking her thumb in highschool. Can you guess who?
