Correct. I have zero objection if a woman breastfeeds in public. There are plenty of ways to do it without flaunting it.
If the mother is not making an exhibition of it, the store should leave her the hell alone. Especially a store a store like Target which sells things for infants.
You are so right. If she "flopped it out" for the entire world to see and didn't make an effort to be discreet, I can understand if the store asked her to "take it to her car", etc. If she did it right and sat in the cafe or Starbucks, etc, neither Target nor their customers would have even known a baby was being fed.
