We did a lot of baby wearing. I found I could stand or walk and nurse very discreetly if I wore a nursing top (so my tummy was still covered.) This allowed the whole family to keep going when we wanted to.
We still found spots to sit--but a sling helped our family a lot since both kids were frequent nursers and I sometimes wanted to keep going.
(My mother once asked to take a baby and carry her for a while--But she was nursing and had been for the previous forty minutes in the sling while we shopped. My own mom had no idea she was nursing.)
My kids were very large babies, so this only worked well for about 10 months--when they were about 20 lbs. We had to get creative after that.
I have one photo of my dd at about 18 months in my otsbh sling--recently, she was looking at the photo and asking about it. It took ME a few minutes later to realize where we were and what she was doing. We had been hiking and she got tired and cranking wanted to nurse. So she nursed sitting up in the sling. My husband snapped a photo. It was hard to tell she was nursing.
I tried to be sensitive to others. Nursing (esp toddlers) does make some people uncomfortable. So I always tried to be as discreet as possible--for others sake. But I was never going to hide under a blanket or take my nursling in the bathroom. (I was once asked if I wanted to go in the bathroom at
Walmart. I asked if I was offending someone. I said that I really wouldn't want to eat in the bathroom and I didn't think my baby should. . .)
I agree with the previous poster--you won't see these people again.
But I also think we should try not to offend people. Offensive language, swearing, "sharing" smoke offends me. Those people think they aren't doing anything wrong--But they should be sensitive to others who it bothers.
