I mean yes feeding a baby is important , really it's who ever draws attention to it that's a problem.
It's OK to breast feed a baby in public, but show some sense, a mother should cover herself, not every one wants to watch her feed the baby.
Public breast feeding can be done very discreetly without undue exposure. (A restroom is not a sanitary place to feed an infant.)
Or maybe women are just tired of strangers sexualizing their bodies.
no one talks about what you do behind closed doors
Feed that baby!
