Hosanna
maybe I can give u some inputs on travelling to Australia cos just came back from Perth.
For the flights, I let ds sucks on his pacifier and take occasionally sip of water or juice during take-off and landing, so no problem at all with ear pressure. For sleep, I reserved a bassinet when I book the ticket. Was lucky to get the bassinet on both to-and-fro flights cos many babies onboard and some din manage to get the bassinet so got to carry baby in arms.
We stayed in self-contained apartment with kitchen facilities, so we can cook if we want. My ds takes rice now, so we bought rice from the supermarket in Perth (apparently quite common nowadays), and use the pot and stove provided. If we eat out, I'll feed pasta or any type of noodle or bread.
Yes, bring enough overnight diapers unless u are currently using Huggies or Babylove (only these 2 brands in australia). I made a mistake of not bringing enough pampers, so haowen had to put up with a few "wet" nights.
As for medication, I brought those for fever, cough, stomach wind as standby.
Ya, a lot of stuff to pack. So end up the luggage for hw is a hefty 26-inch, 20 kg load.
