It's been my experience that children often to begin to ween themselves close the the 1 year mark b/c they are not needing the milk like they did before. It's not going to hurt them (duh!) but it's no longer essential. I nursed my 2 both for 1 year each and weened w/o any issues; they even were giving up feedings before I was ready, on account of engorgement!
By that age, I was nursing them probably 3x a day (Morning, noon, night.)
If she's eating a healthy balance of other nutritional solids, she should be fine, in my opinion, with the 1 nursing a day, then just give it up when she's 12 months.
Additionally, I see that you're looking for a PT position. I'd like to talk to you about that, as I'm currently looking for a couple of moms to join my team, as I'm a SAHM that has an international business from home and I train other moms through our simple, proven, success system that includes ongoing training and support. If this sounds like something that you might want to talk more about, message me.
