10 Week Sleep Regression

My 10 week old has gone from sleeping a 9.5 hour stretch at night (1 or 2 wakes before, but not to feed) to 21 wake ups in the past two nights! Talk about a regression. Now, she won’t go for more then an hour without a wake up. Anyone experienced anything similar? Suggestions?

same bedtime routine as every night

swaddled, pacifier, seems like a self soothing problem? But she seems too young for that.
