We apply the recently proposed transfer matrix formalism to two-dimensional quantum gravity coupled to (2, 2k - 1) minimal models. We find that the propagation of a parent universe in geodesic (euclidean) time is accompanied by continual emission of baby universes and derive a distribution function describing their sizes. The k → ∞ (c → -∞) limit is generally thought to correspond to classical geometry, and we indeed find a classical peak in the universe distribution function. However, we also observe dramatic quantum effects associated wiht baby universes at finite length scales.
