Like Lulu I didn't care. I BF my youngest beyond 2 years and my own mother seemed the most perplexed as to why i would bother... sad coming from a nurse... and my child's grandmother who should be thrilled that he is reciving something so valuable.

I tend to only value a person's opinion if i feel that it's given with an educated perspective and/or with compassion... or at the very least if it's said politely. If those elements are missing then their opinion means very little... I smile and nod if they aren't likely to listen to my opinion and tactfully share my opinion if feel they might be receptive.
