my baby keeps on doing watery potty every time he cries any solutions and he has rashes over the butt hole which cream should I apply suggest

A. For rashes you can apply Boroline antiseptic cream and you have not mentioned the age of the child so I don’t know what can be the reason behind motion or frequent motion or loose motion so just to be more sure about the situation it is better for you to conduct a stool test for your child
