No, I never have, but I only have one child and don’t have a car.
My GF, the youngest of three, was frequently forgotten as a child. She has many memories of sitting on the steps of the church of the shopping centre for ages (probably not actually hours, although you never know, it might have been) until her parents came back for her.
One time last year, when my daughter was nine, I asked my partner to collect her from afterschool club. Time came when she was supposed to be collected, and nobody turned up. They called me - but they hadn’t updated my records with my new number, even though it was on their paperwork - I checked later. They called my partner, but she’d forgotten she was supposed to collect my daughter, and had left her phone in another room while she slept, with a migraine. They called my third contact number, my daughter’s grandmother, but her phone was off because she was working at a hospital. So they called the police and dropped her off at the station.
The police took all the numbers (except my real number), called them, and got through to my partner. She wasn’t allowed to collect my daughter, because she’s not her legal guardian. She also wasn’t allowed to even see my daughter, at the police station a few minutes’ walk from our house. So my partner sat on a bench inches away from my daughter, and gave them my current number. That was the first I heard of this. I left work, ran down and fetched her, got an hour’s lecture about ‘always leaving my phone on and always leaving the correct number,’ and we got told that we’d been flagged on the child protection register.
My daughter was without a parent for 30 minutes.
I’d have to say, it would be alien to me to forget my daughter for even a second. But perhaps that’s just because I’ve never been in a situation where that was likely. I’d never get the chance to!
Seriously, though, she’s always on the back of my mind now, too, even though she’s ten, but sometimes she’s at school, so she’s not always with me. If this woman thought she’d dropped her daughter off at daycare, then her daughter would be at the back of her mind - wondering how she was enjoying daycare, whether she was playing with lego, how she was getting on with the other kids and so on. 
One thing’s for sure: the older child, and any subsequent children, aren’t going to be forgotten.
