Hi there, it is possible that she still needs two NFs at this age, but there are parts of your post that make it sound like a prop issue as well.
I'm assuming she's FF, as you mention her taking a bottle? Does she take full feeds during the day? Is she taking solids well?
You also mention that she doesn't need the bottle to fall asleep at naps and BT. Is she an independent sleeper? Can you post what her routine typically looks like during the day?
Is she currently teething? Any developmental stuff going on, i.e. starting to crawl, pushing up to sitting, etc?
