you know its funny , you never see a balinese baby in a nappy ! i noticed that the last 2 times we were there , lucky you already got your answer , cause i wasnt sure , but now i think of it ,the big matahari in kuta sells all baby item 10 times cheaper than you can buy them here , even the baby powder ! johnson & johnson , cussons , i stock up on all my toiletries and bring them home with me and save heaps.
pack very lightly , you can buy them clothes for nearly nothing , and leave heaps of room in your suitcases for all the stuff you find that you will want to stock up on, pack for 3 days max , buy the rest while your there, for a few dollars.
i think they do have huggies too you know !
good luck carting the little one around......
