A new framework for quantum Hall skyrmions in O(4) nonlinear sigma model is
studied here. The size and energy of the skyrmions are determined incorporating
the quartic stability term in the Lagrangian. Moreover, the introduction of a
$\theta$-term determines the spin and statistics of these skyrmions.
