How Do You Let Your LO Sleep

My girl turning 7 months soon. Morning time, she can sleep on her own. But I feel very challenging during evening - night time, coz she refuse to sleep. She will whine, scream and seek for attention. Last time after latch I will put her back to her bed she will play and fall asleep. But now even though she is rubbing eye and yawning. But still dw to sleep.
