I was blessed with baby oy on this june 29. He is grunting quite often in a day . He makes noises while sleeping in day time and his stomach will go insidewhile breething. He is taking feeding good enough . But initial first 1 minute he was not comfortable. After 2 mnts he can take breast feeding easily . But use to make noice slightly .i use to give formula feed 3 times a day. After formula feed ,he use to make grunting soind more. And i was in tense . I consulted peditrician andsaid all this He said there was no mucus in his nose . Its normal to make grunting till 6 to 8 months . Is it normal really or he is having oxygen probs .pls suggest me
