A boy who has been diagnosed with leukemia for the second time is about to celebrate his seventh birthday, and wants to receive cards from his favorite heroes; police and firefighters. Tyler Seddon, 6, is undergoing chemotherapy while doctors search for a bone marrow donor, according to WCVB. “He goes crazy over firefighters and police,” said Tyler’s mother, Rachel. “We want this to be a special birthday, because you never know what could be next.”

He is a huge fan of all Firefighters. His mother is asking firemen from all over the country to send this child a birthday card. They have set up a Facebook page called Tyler’s troops.

This Facebook Page and a GoFundMe account have been set up to keep the community updated on Tyler’s progress and help with donations as he awaits his birthday, which is March 6.

Birthday cards for Tyler can be sent to 96 South Main Street, Pascoag, R.I. 02859.
