It would really help to know how old your baby is before anyone can truly offer advice. If it's a tiny baby, then it's probably not possible. My son was sleeping through the night at 3 months old, but he's the exception to the rule. My other two were definitely not sleeping earlier.
If it's an older baby you can try to have a bedtime routine. Bathtime, followed by reading, rocking, singing, etc. and then laid down for the night.
