Anyone elses baby fighting sleep?

11 weeks old. Shes been fighting sleep the past few weeks. Wont nap more than 10 mins at a time during the day. Sleeps a good solid 8-10 hours at night. She doesnt want to fall asleep to anything anymore. She used to fall asleep to lullabies and vibration on her bassinet. Now she fights it. I have to hold her in an upright position on my chest and sway back and forth while kissing her forehead to get her to fall asleep. And will wake up after about 10-20 mins after being put down.
