Cakey, the soft part is the pulp that has the seeds. The texture of the pulp is not easy for kids to eat and swallow even if it is blended up, thus removing it first would be better. You can introduce this when the kid is older.
Stem part? It means you are only feeding the flesh of the tomato. Just to let the kid have the taste of tomatoes. You can add in the skin and pulp when he/she can chew.
Tomato is not considered an acidic fruit
Milkmilk,
The way to make any food tasty is to use stock. I personally always get chicken bones or pork bones to cook stock and freeze them. Take them out to use when you need them instead of having to boil stock everyday. Natural and cheap.
Ikan bilis provides a good source of calcium. However, it depends on the source of the ikan bilis powder. I have seen commercial ikan bilis powders that are UNSALTED, which means they are not salty. Just take note.
Alternatively, you might want to buy ikan bilis, wash them, sun them to dry them and either blend it up yourself, or bring it to the medical hall to mill it into powder form. I normally do this for brown rice (you can get organic brown rice, mill it into powder and feed it as cereal, it doesnt come with all the flavourings and colourings that commercial products have).
It will be good if you can feed fruits everyday. Make it a habit to have fruits after meal from young. It is good to give different variaties, but please bear in mind the texture and ability of your child to swallow the fruit safely.
Jkids, some kids that are sensitive to scallops will have allergy. Scallops do not cause the allergy, but trigger the allergy.
