There are many different places you may choose to put your baby down to sleep at night or during naps. Most families will go through several different arrangements during the first few months of baby's life.
For: One choice is to share your own bed with your baby. This has benefits for the parents in not having to get up every time baby cries. Feeding (particularly nursing) can be done easily while still in bed, and baby is often more likely to go back to sleep if they are quickly comforted by the presence of Mom and Dad, even if they are still asleep.
Against: No matter where your baby sleeps, you are going to be woken up during the night. If you have your own bed to yourself, you may be able to sleep better in the times you do have in bed. If the baby is bottle-feeding, it can be more disruptive to get up and leave your baby in the bed alone when you make the bottle. Both parents are more affected when baby is in the bed, as opposed to only one parent getting up at a time, as well as affecting one-on-one time parents have together.
In the parents' bedroom
For: You may choose to set up a bassinet or crib in your bedroom for your baby to sleep in. This can be convenient as you do not have far to go to get to baby when they wake up at night. You can also respond faster before baby gets too upset, being close on hand and better able to monitor baby's sleep patterns. If you have other children in the house, it can help to have baby in a separate room, at least in the beginning, to keep from disturbing the other children as much.
Against: Again, it can interrupt what precious sleep time you do have in your room if you are listening to the baby sleeping. In some homes, it can be difficult to arrange furniture in such a way to have enough space both for baby's bed and Mom and Dad's bed and other furniture.
In baby's own room
For: It can be beneficial to put your child in their own bed, in their own room from the very beginning. They can sleep undisturbed by other family members' noises and movements. It can also be helpful to have a well-established sleeping place and routine that will not be changed as much as baby gets older.
Against: It can be harder to monitor your child's sleep and well-being if the baby is in a separate room. Parents have to go farther to take care of the baby during the night, causing for more time awake during late hours. In some homes, it may not be possible to put baby in their own room because there simply aren't enough extra rooms in the house.
