BFing Mommas - how often is your baby nursing?

My babe is almost 7 months and started solids at 5 months. The girl LOVES to eat. She only nurses before naps during the day so 2-3 times and then 2-4 times at night depending how her day went. Not sure if this is enough, seems like she's losing interest in nursing but still too early to transition. She eats 3 solid meals and some snacks each day too with the odd bottle of "juice" (water with a splash of real fruit juice). pumping is a task and I don't want to use up my small stash so I don't want to give her a bottle of my milk and no interest in giving her any formula.
