I am planning on taking all my nappies and inserts with me to OZ when we go in 2 weeks for 2 weeks. I can wash them no problem over there (infact they will get a good dose or sunshine there) and it is going to be quite warm so Josh will probably just wear a nappy and a singlet or t shirt. And everyone knows a cloth nappy looks so much cuter with just a shirt on. 
But we have 4 hours on the plane (that is after over 24 hours after we leave home too), would you use sposies for the time I am in NZ (and staying at someone place who uses cloth), or use cloth and pack the wet ones into checked baggage so we don't have to worry about the smell on the plane (other than the ones we use on the plane (all going well it is only one as I am stuffing it with heaps of hemp)??
