A pregnant mom and her 2-year-old son were killed yesterday during a small fire at their Queens home, authorities said.

Linda Anderson, 24, and her son, Ayden Hayes, died after a blaze broke out around 4:30 a.m. in their second-floor apartment on Anderson Road near 180th Street in Springfield Gardens.

Anderson was found dead at the scene, FDNY officials said.

Her son was still alive when firefighters arrived, but died shortly afterward on the way to Queens General Hospital.

A heartbroken Rondel Hayes, Ayden’s dad, was at the scene staring at the burned building.

“My son would have turned 3 in October,” reflected Hayes, who learned about the blaze through a text from his sister.
