When my daughters were babies, we would take them wherever we went. If they began to fuss or cry, one of us would promptly remove them from the room/restaurant/market/wherever. Not because we felt their crying or fussing was a bad thing. No, it's a perfectly normal occurrence for infants and toddlers. We removed them as a courtesy to others who we felt did not need to be as tolerant as we were with our children's noise. In consequence, my daughters know that other people are not as wildly in love with their racket or with them as we are. Nor should they be expected to be.
