SO who's got one for their toddler?

Who's had a toddler in one???

We're about to get one as Mateauz is scared witless of the big bed but decided to day to jump head first out of his cot making a nice mess of blood all over his face. Im worried about his head and getting injuries and cause of the blood and his crying i havent let him go to sleep

SOOOOO

Would like to know what peoples thoughts on these beds and if the transition was long, bad, good ... you get what I mean
