Place pork ribs and chicken bones in a pot of water (enough water to cover the bones) and bring the water to a boil.
Discard the water (which should be full of scum and impurities) and place the pork ribs and chicken bones into a soup bag together with the red dates and dried cuttlefish.
Place all the ingredients into a slow cooker and slow-cook on LOW for 6-8hours.
Remove the soup bag.
Add salt to taste if necessary (the soup's got a natural sweetness already).
Notes
1. Skip the dried cuttlefish for tots below 18mths.
2. If boiling on stove-top, increase water to 3-3.5L. Bring the soup to a boil and simmer for at least 2 hours.
