This product has a slightly more elevated cleansing effect as Kids above 3 do go out and play much more. Sweating also tends to increase after 2+ years as the skin and sweat glands start to develop. If you are happy with the current product you may continue to use it. IF you find that your child is getting more sweaty or grimy due to increased activity, you may switch to the Krya Kids bodywash product.
Our choornam formats (powder) have shelf life of 1 year. Our Krya Kids love their krya "mud bath" - it is not that much more inconvenient / time consuming compared to a soap / liquid format - and it is much better for skin. Do try it.
