This is not be allowed today, to roll back baby training 50 years - so there is no danger about what is now acceptable to moderns. Only one class fits - the Amish/Mennonites with many babies and a clear concept of Christian Faith. They are expanding, unlike the rest of all groups.
Most realize that the best nursery for a baby is the mother, the best source of real nutrition (aka breast-feeding) and the best the way to unite the mother and newborn.
Next in line is the toddler and young child. Who learns more? Both groups have remarkable gifts of learning, guiding the mother, enjoying good nutrition after nursing is over, learning an enormous amount of facts and emotions, and growing up in increments.
If children would grow in groups - not just "one and done" - they would gather the remarkable differences in birth order. However, one and done has gone from that category to "no babies at all." Groups of four were rather scarce after WWII, and two were more likely. The four Jacksons won the "most sons" category (3 out of 4 children) at the Moline Disciples of Christ Church (no longer).
