At first, this tip looks rather logical: parents lie their baby on their stomach so that the infant won’t choke. But doctors have found out that this is more dangerous than having them sleep on their back because:this pose may cause airway obstruction;if a baby sleeps on their tummy, there’s a lot of pressure on their abdomen and their thoracic diaphragm;this pose may also cause overheating.That’s why experts recommend that parents lie their children on their back and turn their head to one side.
