Nursing less?

Avery

I wondering if this is my daughter weaning herself off my boob but she is almost 10 months old and she's slowing nursing less. Yesterday she nursed twice and not really to eat, just to fall asleep. She doesn't drink a bottle or use a binky. So I'm sitting here confused , is she not eating because she is teething. Is she weaning herself off. Idk...I'm over here think how I'm gonna start putting her to bed....
