Zen
my gal lost 500g too! Next time u go hols, must bring meds. We brought all meds including nurofen. So even when she had high fever, we had med for her. The only one I forgot to bring is the suppository so end up we had to buy from their local pharmacy. Theirs is super strong type, take half every 24hrs.
My gal was also upset during the trip and cried through out the nights. So totally understand how u feel. My boy on the other hand enjoyed it so much that when I ask him if he prefers japan or singapore, he says japan. My gal was also terrified of bathing there. When she came back, she screamed for first day when my hb bathed her. But now that everything is back to the old routine, she's alright with me bathing her.
We went out to eat everyday and we got the sack seat with us. So she was still alright sitting there. We ate in big restaurants and shokudo (food court). Only 1 time we went to those vending machine type of small restaurant. But it was still spacious enough for us to bring in our strollers.
