Weaning?

I'm not sure, but I think my baby girl is self-weaning.  I know, it is so sad, she is only 9 months old. Definitely not like her brother, who just might still be nursing if I hadn't stopped him at 19 months.
She has barely been nursing at all these last couple of days.  Yesterday only once during the day and today twice.  Tonight she didn't even want to really nurse before bed!!
I am a little sad, wait, who am I kidding, I am really sad.  I wanted her to make it to at least 1 year.
