Hi, thanks for using healthcare magic
The small amount of blood you would have seen when sneezing
is due to inflammation of the nasal passages as a result of the viral infection, it will resolve.
At his age , you can consider the use of normal saline drops or spray to help with the nasal congestion
, baby rubs would also help and may provide some relief for the coughing as well.
You may want to consider propping him up in his crib, this would help with the nasal congestion and reduce coughing when preventing secretions from going into his throat.
It is also important that he remains hydrated.
Because of his age, do not hesitate to have him assessed if you remain concerned.
I hope this helps
