Sad to see baby cant sleep well

My 8 weeks baby seems catnapping and difficult to put her into nap It is not that i force her to nap but she is very tired and sleepy so i help her to sleep by rocking, singing lullaby and all but within 10-30 mins she is awake and start being cranky and keep yawning. Any way to help her nap at least an hour? Sad to see baby cant sleep well
