So I'm about 32 w with my third baby girl. My first baby was formula fed and my second I tried breastfeeding but my left nipple was cracked so bad I stopped I guess had something to do with her latch?anyways I feel like the last time I wasint fully prepared and wanted to see if anyone can give me a brief list of supply's I will need this time around and if u think a nipple shield would help me better so I dont have the same problem?
