Those are pretty high ratios - and I agree detrimental to children and very hard on the caregivers. As we're talking about stem mothers, I was thinking more of ratios I've seen in the SF for more affluent parents: * Private nanny offering 1:1 time until kid is 2 or so (better option than daycare) or daycare with 1:3 ratio for infants * Preschool for kids older than 2 with a 1:6 ratio. My general read is that some childcare providers can outperform some parents. Yes, it's not their kid, but the higher passion for education can more than outweigh that.
