Please tell me that there is no way this could have happened

Just went upstairs and DD (21months) was at the top of the stairs. Thank god I shut the gate out of habit. I had put her in her cot not 10 mins before. No one else in the house except DS (6month)
I cannot see how she could have got out. The rail comes to her chin. Maybe a couple of inches below.
What can I do?

Both mine had come out of cots long before they could manage to climb out. Both in beds before 20 months I'm sure.

Ds2 did fall out of his cot when he was 4 months. Dp couldn't have put the bars on properly because I woke one night to awful screaming and found him laying on the floor under cot with the side swinging off!
He was ok, lucky they bounce ;-)
