Rachael, is looking for a baby sitter in Sydenham hill

Hi, I’m looking for a French speaking babysitter to take over from our full day nanny (she leaves at 8) until we get home. Our nanny will make dinner and get the kids ready for bed, but I will need someone who can read them a story and put them to bed. We are a half French family so looking for someone to help the girls practice their French - native speakers only please.
