Hi,

You are right - you don't need us to tell you. You are doing the right thing. Your mother is wrong. Depending how you feel about it you could just smile sweetly and nod, then do your own thing. Or you could, set her straight, or give her some great info such as the Australian Breastfeeding Association's "Grandparents" booklet.
You are doing a fabulous job with your little one
