  Baby Skyrmions are topological solitons in a (2+1)-dimensional field theory
which resembles the Skyrme model in important respects. We apply some of the
techniques and approximations commonly used in discussions of the Skyrme model
to the dynamics of baby Skyrmions and directly test them against numerical
simulations. Specifically we study the effect of spin on the shape of a single
baby Skyrmion, the dependence of the forces between two baby Skyrmions on the
baby Skyrmions' relative orientation and the forces between two baby Skyrmions
when one of them is spinning.
