It's really hard to answer this question when you don't mention the age of the baby. I'm guessing you have an infant. If it's a brand new newborn, keep in mind they have a 24 hour cycle, not a day cycle and a night cycle. At night time when a baby needs to be fed, it's best to just take care of business and no other stimulation - no talking to or playing with the baby, keep the lights very dim, don't watch tv during feeding. The other thing is that it's okay for baby to be up. If she's not crying and you know she's not hungry, it's fine for her to just hang out in the crib in her own room or pack n play in the living room so mom and dad can get some sleep.
Good luck!
