Personally as a matter of convenience to me it makes better sense to make sure a child (who can’t order from the menu) be well fed before going out. That way mom can enjoy her meal and she can be fairly certain her child will not be overly fussy. She may not have been able to find a secluded area. Which I agree for the sake of the child’s comfort is the best choice. Not a bathroom unless it is a lounge.
I don’t find it immodest for a woman to nurse in public even when part of the breast may get exposed. A baby’s head covers a lot. I get that others disagree. What I take issue with is those who have made this about her looks. Don’t claim it is a disgusting immodest insult to public decorum because she is obese. Either it is or it isn’t no matter the beauty rating of the mom.
Put it this way there is no beauty rating for this one. The only thing that would suit this is a burka or a pile of mud.
