Weaning question: decrease in bottles, not breastfeeding, with increase in foods.

I have a question re the weaning process: I know milk should be the baby's main source of nutrition until about 12 months. My LO is a few weeks shy of 11 months. Over the last 2 weeks she has been decreasing her usual 3 five ounce bottles per day while I work (about 10 hrs) to 2 bottles. Only on 1 day did she only have 1 bottle, but I chalked that up to being sick or teething pain (where she just wants to chew on the bottle nipple but not drink the bottle). But today she has only had 1 bottle, about 4 oz worth. I heard she's been happy today, not irritable, cranky, no teething pain. She has had more food over the past couple of days, but I chalked that up to the holidays, (all we do is sit down and eat at everyone's house allllll day). But back to work these past 2 days, she had 8 oz yesterday and 4 oz today (along with 3 oz yogurt, half a kiwi, and a ton for dinner: spinach, chicken, dirty rice, broccoli.. I know her Pedi said, at the 9 mo appt, this is when baby starts tot take less milk and more food, I just didn't expect it to happen over such a quick time period. 2 weeks!? FWIW she does seem to be nursing more frequently at night, multiple times from 1-6 am (we cosleep, so I'm not really sure how often exactly). But it's been like that for months now, even when she took 15 oz when I worked. Could she be reverse cycling? On my days off, she breastfeeds less than she used to 2 months ago, but not just on e per day. Also, wet diapers and poops remain about the same: 6 wets per day, 1 poop every other day. Thoughts?
