When Did You Choose To Wean Your Child From Breastfeeding And Why?

I just have this feeling, maybe my maternal instinct, that my daughter and I are done breastfeeding. She is 9 months old. She is so much more happy and content after a bottle, and I’ve got to admit that I’m getting tired of it (breastfeeding). I don’t love my daughter any less, I just feel like this is over. Is it bad to feel this way? Did anybody else stop because they wanted to and not because they had to?
