It’s a dilemma most of us have probably faced at one time or another: Should you get involved when you see a parent or caregiver yelling at a crying child? For Liv Tyler, the answer is definitely yes. On Wednesday, paparazzi captured the actress as she confronted an older woman who was allegedly being less than motherly (or, in this case, grandmotherly) to a bawling toddler.

Liv, who is mom to 4-year-old son Milo, was driving solo in Los Angeles when she saw the woman hollering and swatting the stroller-bound tyke on the chest, according to X17Online.com, which says she immediately braked, made a U-turn and hopped out to give the lady a piece of her mind.

“You can’t do that!” she reportedly told the woman. “I’m going to call the police. I’m going to call child services!”

But there was apparently a language barrier, because the ostensible babysitter repeatedly replied, “No entiendo” (“I don’t understand”).

Tyler was snapped bending over to console the distressed tot before heading back to her car, looking visibly upset.

“When I saw that, I couldn’t take it,” she told the shutterbugs. “I had to do something.”

When we contacted Liv’s rep for comment, he confirmed X17′s account of the incident.

This appears to be an example of the statuesque star putting her passion for child advocacy into immediate action: She’s been a UNICEF ambassador since 2003.
