My son has just started solids - can we order food for him at a restaurant or is it better to carry purees with us?

I will avoid giving outside food too, for baby below 2 years old. Reasons being the salt level of outside food is very high. And most of the outside food are added with seasonings which will burden little one's digestive system. You can prepare your own snacks e.g. biscuits, fruits, bread, porridge, and etc to feed your baby.
