mini woven baskets/boxes then put some lil sweets inside them or
for the girls: burloloys (wooven necklace, earrings, bracelets etc - good for spring/summer)!!! lots in divisoria/quiapo... very cheap when u buy it in bulk

for more ideas: go to SM Kultura (quite expensive there though)

or boys: maybe a mini jeepney figurine or any wooden thing? hehehe depends on u though...
