If it's modern double pane glass the baby isn't getting any uv. But I'm taking a stab in the dark and saying the soil you repotted her in is significantly different from the original soil. Just shock is all.

The potting mix -- or whatever it's in -- appears bone dry.

Stick your finger in it to determine if wet or dry.

Take it out of the sun until it recovers. Looks like a greenhouse cutting that needs to be hardened off.
