Terrified

So we are driving to work this morning and I look up at a house across the road. 2nd floor, but maybe third b/c the house is on a steepish incline and I think the front of the house is 3 floors but you see two from the side. And I see a babies head in the window. In front of a screen. On the second floor. Poised as if crawling but I can only see hands and a head pressing the screen. I literally cry out "OH MY GOD, there's a baby in the window."

Doug turns the car around in this very slow plodding methodical way and I am BURNING to open the door. "Oh my god, oh my god" I'm chanting - OUT LOUD. It's a minute and feels like a thousand years. We turn around and I look up. The "baby" is about 19 months and he is now STANDING in the window, pushing on the screen, trying to fiddle with the top, full body pressed to the screen, STANDING IN THE WINDOW.

I am now racing towards the house. I call up, but not in a panic voice, "Get back from the window, honey, get down" real calm like - and I'm now at the door. I start ringing the bell, knocking FIRMLY on the door. RING, knock, knock, ring. . .
NOTHING. I look at Doug, "is he still in the window" Doug's standing back so he can react. "Yes"

I start pounding pounding on the door so I think my hand is going to break. Now I'm losing it. No ones opening up. "Hello, hello" I'm calling out "HELLO" "THE BABIES IN THE WINDOW"

Truly so frigging horrific I want to freak out. I'm ready to CLIMB on the roof. We start looking for ways to get up. There's a wire fence and concrete. We can't get any closer. If the window goes, we can't catch him because there's a peaked porch under and he could go any one of three ways.

I am now pounding and ready to run around to the front to look for another door. Anything. Then I see Doug lift his hand.

"Ok, oh, ok, we were just afraid he was going to fall out" and then that was it. Someone came in the room, and got the baby out of the window. I looked up and no one was there. And then we left. I asked Doug, "What happened" and he said "I saw a hand snake out and grab him"

And now I am so freaked out it's not funny. Whoever she was, Doug said she was a blond woman, whoever she was didn't see his little body bowing the screen out. Is she going to get railings? bars? Does she know that if we weren't out there pounding, and if she hadn't come in to look out the window, that he likely could have fallen? I wanted to cry. I don't know what to do. I mean, I want to assume it scared her and that shne'll take action - but how do I know? Nor do I want to call the poilice b/c that's not fair if it was an honest to goodnedss he slipped out for a SECOND. Mom's - what do I do??? Is it an honest accident or do I leave a note saying anything? What would you do?
