I was able to buy the toddler rail for our Boavita Peyton 5yr after we bought the crib. We never used the crib as a bed for DD1 so we didn't need it but D2 is a tiny thing and we were able to use this crib as a toddler bed and got lucky that the rail was still available. We looked at some of the other cheaper alternatives but like PP said many don't work if your crib doesn't meet certain specifications.
