Hello, my baby crawls daily her knees hands have become black which soap or body wash should be preferred & lotion as well? please help me

A. whenever you are choosing any baby product whether it is baby oil lotion soap powder shampoo or xany product, you have to see whether the child is having any allergy after its usage or not. so if the child is comfortable you can use it but if the child develops allergyx or any other problem then go for another brand. .
