(As impressed upon me by my wise wife)

Dads, has the child* sleeping in a crib just woken up crying? Don’t go get him/her. Wait** a while. Let them calm down.

A child who wakes up crying is still tired. And if you get them up, you’ll reinforce two ideas:
(1) that crying will help him/her their way, and
(2) the crib is a troubling place from which they should be saved.

If you let them stay, they might just fall asleep again and get some needed rest.

You want to get a child out of the crib when they’re happy.

* Not a two-week-old infant
** Obviously, waiting while they cry for three hours would be unwise.
