We discuss early cosmology in theories where the scale of quantum gravity is close to the TeV scale. In such theories the standard model fields are localized to a (3+1)-dimensional wall with n new transverse sub-millimeter sized spatial dimensions. We present the aspects of asymmetric inflation before the stabilization of internal dimensions and the spectrum and magnitude of density perturbations produced during it, the post-inflation era of contraction of our world while the internal dimensions evolve to their final ``large'' radius, and the exit from contraction to a usual FRW universe. We show that the production of gravitons in the bulk during these two eras is greatly suppresed, and define the radion moduli problem and possibilities for its solution.
