Bus companys dont make the law when it comes to pushchaires or buggys on busses thats a goverment and federal law.
It states that if the bus has steps then pushchairs, prams, wheelchairs must be folded and stored in a safe out of the way manner that it will not affect or hinder an emergency evacuation. which meens the space front to rear of the bus between the seats must be kept clear. On Lowfloor buses there is space for wheelchairs, pushchairs and OAP scooters, however a pushchair must be folded and stored if a person in a wheelchair needs that space.
When it comes to breast feeding on busses the only time i have asked someone to stop is because of when a passenger has come up to me and asked me to stop them and done it just to cover my own ass.
