Tot wanders into traffic

An adorable 2-year-old Bronx girl wandered alone out of her home yesterday and onto a traffic-heavy street — where she was scooped up by a quick-thinking good Samaritan.

“As a father, this is nuts!” fumed Pepsi deliveryman Martin Rodriguez, 32, who spotted Samira Dawson teetering barefoot across busy White Plains Road in Parkchester wearing just a onesie and a diaper. “I have a little girl the same age and it crushed me to see this.”

At 9:10 a.m. yesterday, Samira somehow left her family’s apartment on Guerlain Street undetected, walked outside and strolled across White Plains Road.

Then, “A lady grabbed her,” Rodriguez said. The unidentified woman gave Samira to a Parkchester public-safety sergeant, who called cops.

“She appeared like a bubbly child,” said Officer Harry Kwan, who draped his coat around Samira.

Samira’s worried-looking brother, Davante Valentine, 20, showed up at the scene at 9:39 a.m.

“I don’t know what happened,” Valentine told The Post. “All I know is I was sleeping and my [18-year-old brother] was supposed to be watching her and he left the house without telling me.”
