My baby in sleep makes snoring sounds as if he has difficulty breathing r like some blockage. He breathes normal wen not sleeping. Anything to worry?

Maybe. Make a movie. To show the pediatrician what's happening, the parents can make a movie of the shirtless baby's breathing. Show the face, chest, and tummy at the same time, so the doctor can see how everything moves during breathing. A minute into the movie, open the mouth to show how the breathing changes; and then a minute later, close the mouth to show how the breathing changes again.
