What does the law say?
The new Equality Act says treating a woman unfavourably because she is breastfeeding is an act of sex discrimination. The new Equality act applies to anyone providing services, benefits, facilities and premises to the public, public bodies, further and higher education bodies and association.
Service providers include most organisations that deal directly with the public. Service providers must not discriminate, harass or victimise a woman because she is breastfeeding.
Discrimination includes refusing to provide a service, providing a lower standard of service or providing a service on different terms. Therefore, a cafe owner cannot ask you to stop breastfeeding or refuse to serve you.
