Bath water?

Question:water comes from a well, not good enough to drink, what can I put in water so kids can bath, or filter

Answers:
Well, you're really not providing enough information here for a good answer, but I can suggest that you look at "whole house" water filters, as a start.

Paper filter cartridges are good for removing sediment.
Some of these come in different levels of what size sediment they will allow through the filter.
Charcoal filters are usually the type that screen even the smallest particles out -- helping to eliminate some bad odors, and improve the taste of the water. You can even go with a 2-stage filter, which removes the larger sediments before the water hits your charcoal filter. (Which will make the charcoal filter, usually the more expensive filter available, last longer)

Next, you may consider a water 'treatment' product. These are typically products which will help eliminate iron, soften the water, etc. You can use a "whole house" filter before these products, to extend their life, if your water has a large amount of sediment, lime, etc.

Final suggestion, drill a new well. Again, not knowing the details of your water problem, it is hard to say whether this would be the best decision or not. But, often, it is possible to go past a bad pocket of water by drilling deeper.

Good Luck
