If u r with infant, u can bring Liquid on board. As long as reasonable quantity. U can double check with the airline or airports involved if unsure but I had no problems bringing in bottled breastmilk (declared) or even plain hot water in thermos flasks...

Generally a pain to travel with infants... Two thirds of luggage is all their things

No prob. Sometimes travel on plane cannot rely on hot water on board alone as u may need thermos with hot water suddenly at any time when bb hungry. Most airlines people very understanding when there is infant around.

Lol yah, bring so many things also in the end can't do much of your own things during holiday haha
