Hi, baby boy is 7 weeks old and since birth pretty much has been drinking 4/5oz formula recently moved up to 6oz. He was born 9pound 8oz so a big baby who has always had a very good appetite. The last week he caught my 4 year old daughters cold and has had a terrible cough - but the cold itself seems to have settled (no more snotty nose, coughing now and again but not as much) but since he’s been really off his bottles! Yesterday he had 2 bottles all day and only drank 2/3oz, he’s fed a bit more throughout the night but only taking no more than 3oz, he is also what seems getting really stressed when feeding (hitting himself) stopping and starting, crying, and taking about half an hour-45 mins to finish just 3oz. I’m worried and not sure if this is cold related or anything else? Or if it’s normal?
