Western Family looking for a help with experience with babies

We are a family of 4 living in Cyberport area (Pok Fu Lam). We are looking for a helper with excellent experience taking care of babies and with excellent English language skills. This helper will work mainly with the baby as we have another helper who takes care of all the other chores. There is a separate room for this helper and no sharing. A helper with experience working for westerners is highly preferred.
