It talks about a study from 1944 in the US, specifically in Minnesota. How many of those parents were full-time stay-at-home parents, probably typically mothers, who were monitoring the child and helping with potty training?

How many kids nowadays are in daycare?

When there is a 3-to-1 adult-to-child ratio, doing something like this is much more challenging when there's just one adult and one infant.

Absolutely. 3:1 is only common ant absolute top tier daycares. More likely you’ll have 6:1 or 8:1. And even high quality daycares might not help children potty train which is absolutely essential if both parents are working but people want to potty train early. By age 3 kids are moving towards preschool and are more intelligent and have better self awareness and are more reward motivated. I think diaper conspiracy is honestly less likely here than structural advantages and modern life leading to later potty training

I was only talking about infants, and I thought Massachusetts's legal requirement of 3:1 was pretty common everywhere in the US, since one adult taking care of 3 infants seems so difficult... but a quick search shows me it's not! 4:1 is pretty common as a minimum nationally, though.

Definitely. I think that's pretty rare.
