He forgot to drop them off at their day care Friday morning, Rodriguez has told cops — and didn’t realize they were still in the back seat when he parked at the Bronx hospital where he’s a social worker, court papers reveal.

Eight hours later, the twins, Luna and Phoenix, registered an internal temperature of 108 degrees when coroners examined their bodies in their car seats.

“I assumed I dropped them off at day care before I went to work,” Rodriguez told cops at the scene, according to the criminal complaint against him.

“I blanked out!” he cried.
