Yes. A breast is for feeding babies, and someone should be able to feed their baby somewhere comfortable, not a bathroom or somewhere disgusting. Anyone who finds it sexual is just a creep, conditioned to think that way by a broken society, much like how the calf used to be considered raunchy in times where women were expected to cover up. Don't punish women and children for creepy people choosing to sexualise feeding a baby / a body part with no sexual function.
