While some sleep labs are losing beds in favor of home sleep testing, some pediatric labs are expanding. The Baltimore Sun reports on the expansion of the sleep lab at sleep lab at Mount Washington Pediatric Hospital.

Wide awake and full of energy, 4-year-old Kyle Polk munched a cupcake during a grand reopening reception for a newly expanded sleep lab at Mount Washington Pediatric Hospital.

Kyle had his tonsils and adenoids removed July 3 — just as his older brother, Tristan, did two years earlier — to treat obstructive sleep apnea.

They and their parents, Brian and Tamara Polk, both 35, of Havre de Grace, were a poster family at the ribbon-cutting reception on July 10 for the lab, called the Johns Hopkins Pediatric Sleep Center and located at the nonprofit hospital on West Rogers Avenue.
