Which fruit juices found in supermarkets in Manila can be best given to my toddler? Those with less preservatives perhaps?

I suggest you should try juicing fruits instead of buying commercially available ones in the supermarket if you opt for no preservatives. Maybe, you can also try giving your toddler fruit water as simple as orange+water or strawberry+water combinations. You can always add honey if you would like to make it a little sweeter. Here is a link on a good list way of preparing fruit water that you might be interested in:http://www.superhealthykids.com/flavored-water-for-kids/
