gan, i also got nestle samples. start with white rice. my pd advise is start with 1 teaspoon, and slowly add one teaspoon per day up to 5 days. if no allergy reaction means the food is safe to give bb. every 5 days can add new foods..so in case of reaction, we will know what is the cause.
it is also important to introduce foods of different taste.. sweet, sour, salty, bitter etc.
for fruits, its good to start with steaming and puree.. if ok, then use fresh and puree...
baby, i intend to use the plain cereal pack, mix with freshly made puree.. pre packed ones usually alot of preservatives or added artificial flavours.
