My 3 months old baby always sleeps by his tummy? Is it ok to allow him to sleep at night like that ?

When a baby rolls on their own, they seem to say that it is safe for them to lay on their tummy. As long as your child can move the head from side to side without trouble, the baby will instinctively move head to breathe. The fear is more when you have a newborn whom is unable to turn their little head on there own easily. SID's fear is from the suffocation risk that can occur when they do not have certain instincts that they can utilise. My son couldn't sleep without being on his tummy either. But when he used to wake up, he immediately rolled on his back.
