I read about it today on a travel thread on here and I asked dh to look out for it in Holland and Barrat. We are travelling to the US with a 4 yera old and a 1.5 year old. No problem with 4 year old, but I think we may get chucked off the plane at altitude by other passangers when 1.5 year old really gets going. SO I thought I might try the valarium. However, the packet says from 2 years old. This actually doesn't bother me much, but I was wondering if anyone else has used it. Does it work? What is it like? Etc etc!
