is it safe to apply shea butter on 4 months baby?? if yes which brand is best?

A. Hello ma’am If the butter is that you are talking about is specifically made to be used for kids then you can use it otherwise not I was just a trailer simply for the time being to use all the product which are completely based on kids usage like Johnson Himalaya or whatever brand you can think of and later you can change the brand after the age of one year as per your convenience
