I pour about a cup of table salt in my daughter's bath every day and it has made a huge difference. She plays in the water for about 45 minutes and then I wash her like normal. Of course we use lac lotion afterwards, but as for bath time I do not have to scrub her skin at all. The salt makes the dead skin wipe away. Maybe using a smaller amt to start off with can help v/s rubbing salt on her skin.
