We are very kid friendly at our salon. For most salon services, it doesn't really matter if the client has a child with them. It can be awkward, however, when a mom comes in for a Brazilian and has a child with her. Usually we leave the kids downstairs with my husband or a staff member. Occasionally, children do come in the room with their mom. Unless the child is poorly behaved, I could care less.
Today a lady came in with her son & daughter. I offered them some puzzles to play with and showed them a place on the first floor to hang out while I took their mom upstairs. I asked her what her kids thought she was doing at the salon. She told them I was helping her with her groin injury.
Close enough.
