I have a baby squirrel around 3 weeks old and he got milk in his nose and now has all the signs of Pneumonia. What can I do to help him and keep him from dying. He is the only survivor out of three babies. The tree his nest was in was cut down before the hurricane. The ppl waited to see if the mom would return but she never did. My grandparents always raised the baby squirrels that were found but I have never had this issue before. I am heart broken and hoping there is something I can do!
