For the first (almost) two years of my daughter's life my family has been in a very successful nanny share situation. (bumpclubandbeyond.com)
In a typical nanny share, two or more families share one nanny, splitting her salary between them. (policygenius.com)
The only one who was part of my social circle worked part - time during the day (naps, swaps, a small nanny share) but mostly worked at night (worked well for the nature of his job anyway), which is why we never invited him to join us. (skepticalob.com)
