Oh no - hope sassy and annie are feeling better, no to mention W. Is he ok?
Cheshire our trip is Sydney/Blue Mountains/Adelaide, and am in Sydney now. After a MASSIVE meltdown from A yesterday we realised that we had to keep him on NZ, rather than Aus time zones to keep him happy to am sitting in a hotel room at 6pm with a toddler who's been down an hour, having been up since 5! It'z ok though, not like we are going to be spending our evenings partying up a storm anyway.
The flight was fine on account of A sleeping for half of it, so not sure yet if I have any good tips, rather had very good luck! I'll post back after our next three flights ...
Things I've learnt so far though are keep his timezones as normal as possible, and give him lots of time to do nothing. We tried to fit too much in the first day, and he got really grizzly and now have a routine of doing nothing for at least a few hours a day in the hotel room it's working better. Which is counter intuitive when you want to go out and explore as much as poss, but hey ho.
We saw a Koala today and posed A in a photo with it, but then he yelled "eyes" and tried to poke the koala in its eyes. Glad I moved him away quickly. Those claws looked sharp.
