A 2 month-old child having noisy respiration and you feel his sound is coming from chest.this could be a nasal block and puting nasoclear nasal drops 10 times a day before every feed would help .But this sound has persisted for one month and has not affected your child's feeding behaviour so please relax it does not look anything serious .Baby is managing his urine and stool well so the milk intake is appropriate.if you think you need extra top milk then please use a bowl and spoon that's much more hygienic than a bottle.
Then if he is vomiting after feeding is it after coughing or is it otherwise.vomitings are also due to overfeeding.
If you have a family history of skin or respiratory allergy like allergy in you or your parents or on baby's dad or his parents then this sound from chest needs to be evaluated.
