The good news: everything in the first year is a phase
The bad news: crawling can cause sleep issues but more likely, I think she is hitting the early stages of the 2-1 nap transition. Too much day sleep will cause multiple NWing at this age... she isn't tired enough to sleep through the night completely.
How much formula does she take during the day?
Could you post your current day (a full 24 hrs) in EAS format with sleep times, how much she eats and at what time, and typical daily activities? This will help get a better view of her day
Thanks
