Baking soda is calcium hydrogen carbonate. Hard water is usually caused by calcium. Adding baking soda should precipitate some of the calcium out as calcium carbonate making the water softer.

I would think that vinegar could do some help. Hard water is full of minerals and is alkaline. I guess that the acetic acid in vinegar could react some of that away.
Baking soda will buffer the water. This is a help if the pH is out of whack (if the child urinates in the water). Baking soda will also help keep the water clear (Used in swimming pools). But that is not a big topic in a childs bath water.

I use Borax to softer my very hard water & vinegar in the rinse cycle to get all the soap out of the clothes. I don't need dryer sheets anymore!
