'big bed' mishaps

last weekend we got a toddler bed for lumi.  it's adorable and she is excited about it.

except when we put her there to sleep at night.

she will happily read a book with me while lying in her bed, all tucked in.  but when i say good night, she starts crying and gets up, asking plaintively for the 'big bed', which means our bed.  we have a good wide bed, so it's not a problem if she sleeps with us, so we have been just putting her in there instead of having a battle of wills every night.  but she sometimes moves around while she sleeps, and last night while we were reading in the living room we heard a sickening crunch followed by very upset crying.  we ran in there to comfort her, but since the crunch sounded bad and she was crying more than normal (yes, she falls out of bed every couple of weeks), i turned on the light to check for injuries.  she looked ok, so when she calmed down i put her back to sleep, and she stayed reasonably calm and in one place most of the night.  but this morning one side of her face is decidedly puffy and there is a bit of a mark.  oops.
