What's an older mother? You were old when you had them, or you are old now? I was 36 when I had my son, officially classed as an older mother, but I don't feel like it!
I am so grossed out by meat, dairy, bee puke etc, that I have not fallen off the wagon. The very thought of eating something that comes from an animal really repulses me, so I guess I have it easy! I subscribe to various vegan groups and activists on Facebook, it all reiterates what I feel and know, maybe that will help you? I actually forget that we are a minority!
I do not know Anna's definition, but I consider myself an 'older mother' because I had my children at age 40.
As for falling off the wagon...I've never eaten meat, poultry or fish since becoming veggie...but I do fall off the vegan wagon whenever I try to switch from l/o veggie to vegan.
