Fighting sleep

My daughter will be 7 weeks tomorrow and has been fighting sleep (mostly naps) for almost a week. I’m not sure what to do at this point. I’ve tried a lot of things but am wondering if this is just a cognitive growth spurt and she’ll eventually get back to sleeping well again? My son did the same thing around the same age and then eventually just went back to sleeping well. But my daughter is not the same as my son when it comes to sleep. Any chance she’ll outgrow this phase?
