  We present Euclidean wormhole solutions describing possible bridges within
the multiverse. The study is carried out in the framework of the third
quantization. The matter content is modelled through a scalar field which
supports the existence of a whole collection of universes. The instanton
solutions describe Euclidean solutions that connect baby universes with
asymptotically de Sitter universes. We compute the tunnelling probability of
these processes. Considering the current bounds on the energy scale of
inflation and assuming that all the baby universes are nucleated with the same
probability, we draw some conclusions about what are the universes more likely
to tunnel and therefore undergo a standard inflationary era.
