In this paper we consider the stability of some inflating brane-world models in quantum cosmology. It is shown that, whereas the singular model based on the construction of inflating branes from Euclidean five-dimensional anti--de Sitter space is unstable to tensorial cosmological perturbations in the bulk, the nonsingular model which uses a five-dimensional asymptotically anti--de Sitter wormhole to construct the inflating branes is stable to these perturbations.
