I am sure this topic has been done to death, but we are flying to Australia in 4 weeks and I am starting to panic about the flight. My son will be 21 months and I am looking for some good books, toys etc to take along to keep him amused (if that's possible!). Does anyone have any tips for making the journey a little easier? We are flying Singapore Airlines and having a short stopover on both the way over and back. Also, any tips on helping with his jetlag?
