They are dangerous, that's what they are. I have a particular fondness for neodymium magnets but you can really hurt yourself if your flesh is between two of them coming together. If your toddler swallows them you are definitely looking at surgery.
The rare earth magnets have rare earth NdFeB(neodymium) magnets and rare earth SmCo Magnets,more information, you can visit: https://en.wikipedia.org/wiki/Rare-earth_magnet
