The two most valuable things I've learned about parenting infants is:

1) converse with them incessantly, particularly about Kafka and ancient history, regardless of whether you know anything about these subjects or not,

and 2) after you've changed an especially robust diaper, and intend on launching it to the closest garbage receptacle, triple check to make sure it is sealed tightly before flying it through the air.

Plenty more similar advice if you need it.
