Similar to a Kimblehook, but is used with two reins. It is a combination of a Baucher bit and curb bit in one. The rein placed in the snaffle ring will not add any leverage, and the rein in the bottom ring will. This will give the rider the advantage of adding leverage only when needed.
A Baby pelham can also be used with a converter strap/Pelham roundings between the rings to use only a single rein.
