30 minute day naps

Omg I'm about to lose my mind. My nearly 9 week old baby will only nap for maximum 30 minutes at a time during the day for the last few days. I do everything I'm supposed to: adhere to wake times, swaddle, dark room, eat-active-sleep. Nothing I do helps. Even if I get her back to sleep, it will be for less than 30 minutes. I feel like I spend my entire day getting this child to sleep. I can't get anything done. She used to have naps of varying lengths. She sleeps well at night and is generally a very happy girl. But these short catnaps are killing this tired mama. Any advice
