This would be a great question for our "Ask a STM" thread!
I am a Nanny Share Specialist so I am completely biased, but I will say that nanny sharing has incredible benefits! The children gain so many skills from the socialization: empathy, sharing, learning to wait, cooperation, I could go on and on! Many of these skills aren't picked up by solo-care children until close to 2, but in infants and toddlers who have shared from a young age, they emerge so much earlier.As for costs, share nanny rates are 2/3-3/4 of a nanny's full rate. So, for example: if a nanny charges $20 for one solo child, she'd charge each family in a share roughly $15. The families get a discount, and the nanny earns more. After all, she balancing the needs of multiple families and parents, not simply an additional child. For more on that, check out this blog post:https://pareday.com/blog/how-does-share-pay-work/
