i think if you research why it is good to b/f for as long as possible you will be more likely to do it and cope with any 'criticism'. (then perhaps educate)most people dont realise thats its so healthy and the its actually the norm to extend b/f in most of the world....they might be more willing to support you if you let them know the facts.

you could also research 'the truth about formula' for similar reasons..
