my baby is 6weeks old is making gur gurr sounds while feeding. is it phlegm and what should I do

A. thank you for reaching out to ask with this question is very hard to say what it may be without a physical examination however that natural you take a video and then show it of the graduation to your vaccination appointment however please also know that they have a very thin air passage which causes then to make these sound and it gets better with in a few weeks
