have a proper routine for your babies sleep is essential . try to have spaced day naps with enough play time so the baby differntiates between night n day . soon she will sleep 6-7 hrs in the night .

As advised by Babychakra expert Dr Sonali Shivlani (Prenatal) - To teach a baby how to sleep for long stretches in the night a little sleep training is needed. In the daytime keep the environment bright and noisy. Awaken her in a couple of hours for a feed or just cuddle her so that she wakes up. Do not let her sleep for six hours at a stretch. In the night before she sleeps ensure she has a good long feed and keep the atmosphere quiet and dark even if she awakens. Feed her quietly and avoid speaking with her. With a few weeks of this she will learn that night is for sleeping and day is for feeding and playing.

Try keeping your lo awake in the evening between 8-10 pm by talking to them, playing etc
