1.) Once your toddler fell/climbed out of bed how long did you let it continue before switching beds?
Immediately. Is she has fallen out, it's already been too long.
Bed tents were made to keep cats out, not to keep children in. If she's already gotten out once, putting on a crib tent will just increase the chance of entrapment.
2.) Any serious injuries?
Yes, broken arms are the most common. I recently met a 12-month-old boy who broke his arm from climbing out of his crib (it was the first time.)
I am only asking because we are not exactly ready to make the change, mostly mom and dad are not ready.
Sorry, but it's past time.
3.) If you had a child around age two when this happened how did you teach them to stay in the toddler bed? How did you do it?
I know if she gets up she will not stay in her room, cognitively she doesn't seem ready. She loves her crib.
I never tried to make them stay in bed - that sounds too much like trying to teach a pig to sing, but you can give it a shot. If the toddler bed is too expensive (and kids have managed to get their arms trapped in the guard rail and fall over the edge, breaking an arm in the process) - there's always the "mattress on the floor" option. If you can get over the aesthetics, it's really hard to beat in terms of safety. It really is difficult for a child to get injured falling the 3 inches or so from the mattress to the carpet. My kid did this a number of times without ever waking up.
Maybe let her pick out some pretty new sheets so that she'll like the bed "the new way"
Also, IKEA makes some very inexpensive (and adorable) toddler and youth beds with several different safety options. (some that convert from toddler to twin size, some that are a twin bed on a fairly low platform and guard rail).
4.) Should we remove the toys from her room?
No - that basically is punishing her for trying to solve her own problems and doing things all by herself. That's exactly what ought to be encouraged at this age (in general).
And frankly, if she usually plays in her crib for an hour after waking up and hasn't fallen out of her crib until almost two, you've had it awfully easy up to now. :)
