A stranger slugged a grandmother as she took her grandchild for a stroll this week — punching her in broad daylight in an unprovoked Queens αttαᑕk, cops said.

The 65-year-old victim was pushing the child in a stroller around 4:40 p.m. Wednesday on Kissena Boulevard near Franklin Avenue in Flushing when the menace struck her in the face without saying a word, authorities said.

The blow left the victim with facial pain causing redness and swelling, cops said.
