Back when my niece and nephew were young my sister often breast fed in public - she was discreet and rarely were there objections. Several women in our church have in the past or do breast feed in church. Again, rarely anyone objects.

The strange thing is we DID have some people at the restauraunt I worked in that objected to a customer who was breast-feeding - and when I pointed out that my relatives had done the same on numerous occasions no one realized my sister *had* been feeding the child!
