Once your baby has head control and about the same time that he learns to sit on his own, he will learn to roll over.

To relieve choking in an unresponsive infant, first, gently tap the infant's back while holding them face down on your forearm, giving up to five firm back blows between the shoulder blades. If the infant remains unresponsive, carefully turn them over and perform five chest thrusts using two fingers in the center of the chest, just below the nipple line. If the infant does not respond, call emergency services and continue alternating between back blows and chest thrusts until help arrives or the infant begins to breathe.

Self-righting is the ability of an infant to turn their body from face-down to face-up. This helps infants to maintain a clear airway and avoid suffocation if they accidentally roll onto their stomach while sleeping. The ability to self-right also helps infants develop their motor skills and coordination.
