I have a daughter who has a rare form of dwarfism and at about 2 months of age the Drs. decided she might be a dwarf of some sort. A geneticist would be your best bet of diagnosing the child. Dwarfs usually have short arms and legs. My daughter had short limbs but as she grew, she is now proportionate. There are many kinds of dwarfisms. Good luck.
