According to NHS guidelines babies under a year need to have less than 1g of salt per day. A standard beef Oxo cube has 1.05g of salt in it, plain Bisto gravy granules have 0.18g salt in a serving. You could easily make a huge pot of stew using maybe 3g salt in the whole thing!! Unless your LO is going to eat ALL the stew I think you'll be absolutely fine. Yummy, I love stew!!!
