Establishing a breastfeeding area

Dear PAO,

I am planning to start a home barbershop business. I lost my job last year. Being a stay-at-home father, I had to cut my sons’ and nephews’ hair since they have not left the house due to the health crisis. Then, some of our male neighbors also asked me to cut their hair and those of their sons. Now, I am slowly fixing the small space beside our lot to make it into my barbershop. I am also going to hire a couple of my male former co-workers who also lost their jobs last year. Given that the space is very small, do I still need to provide a breastfeeding area? I will only cater to male customers since I do not know how to cut ladies’ hair. In my former employment, there is a breastfeeding area, and my supervisor said it is required. Does this apply in all kinds of businesses?
