I had a bishop whose wife would breastfeed in the middle of sacrament meeting (no cover.) I was amazed and quite impressed. So when I had my first baby I knew it would not be a big deal if I did the same. I was called as YW President at the same time my husband was YM President in that ward...with a 3 month old. I breastfed my baby during Ward Council and not once did I feel uncomfortable or shamed. My baby needed fed and my voice needed to be heard in that meeting. Our Bishop was glad to have me participate and take care of my most important job, motherhood, at the same time.
This was 20ish years ago but I remember my daughter never liked anything over her when she was fed and I hated messing around with covers. I became very adept at beginning and ending a feeding so as not to flash anyone.
