What to do on the plane?

I'm flying with Ryanair to Pisa, Tuscany from London Stansted in August. It's a 3 1/4 hour flight and although I fly kinda frequently (once or twice a year since I was a toddler for ten or eleven years) I get nervous unless I'm pre-occupied with something to do. My little niece who I adore will be there so i would normally play with her but shell be asleep as shes only 2 in Sep. along with my family (about 14 of us) so I'll spend time chatting to them, but I get really scared on planes. What can I do? I have a laptop but I'm not allowed to take it cause I can't fit it in with my baggage (we are only taking hand carry on luggage not check in to save time and money) :L
