Hi Dawn,
It can be hormonal,many women who never breastfed get very tender breasts leading up to their period,but having said that I am a 46 year old who stopped breast feeding a long long time ago and I still get that pang,especially if Im holding a baby.I think its a mix of yearning for that special bond and just being very maternal.Its instictive to hold a baby close to the breast.And what a pure natural feeling that is.
All I can say is that although we as women are unique we are at the same time very much alike.You are most definately not alone in feeling the way you do.
Best of Luck to you.
