I live in central London, a friend from Lincoln was telling me when her daughter was a baby (25 years ago) she used to have a group of local mums (& dads) who belonged to some type of baby sitting exchange club. She would babysit and earn 'points', that she could then 'spend' on getting other people in the club to babysit for her.
Sounded like a really awesome idea as DH and I totally don't get enough 'us time' at the moment, but can't really afford to spend money on babysitters. We both work full-time so we haven't really built up any relationships with local parents.
Does this type of thing exist (in general) and/or do any of you know of any in central London?
