Sleeping position. Is this suitable?

My little baby is going 2 months old. Has heart congenital condition and also on continuous tube feeding 😐 Is this sleeping position a safe position? He seems to always turn to this manner, on the side. He can never be on his back with face up, he will regurge/throw up. Experienced parents with similar past dealings please advice medically and clinically 🙏🏼🙏🏼#firstbaby #advicepls
