I am just wondering how widespread this is. My own DS is a six-foot teenager so doesn't need childcare any longer, but I know that if this had happened 15 years ago I would have joined forces with another single mother, a friend of mine - the kids would have some social interaction, and we would each at least have some time each to work if we shared childcare.
But on social media I see this allowable facility being used primarily between family, not friends, and I am interested how many people are making use of this provision.
