Research shows that a baby's health can improve when they sleep close to their parents. In fact, babies that sleep with their parents have more regular heartbeats and breathing. They even sleep more soundly. And being close to parents is even shown to reduce the risk of SIDS. One of the advantages of bed-sharing, as outlined on the site Kelly Mom, is that babies often get more sleep when they bed-share. Since they're already right next to you, they don't need to fully wake up in order to breastfeed, bottle-feed, or simply be comforted.
