If your child manages to survive into their teenage years, you’ll have made over 85 million parenting mistakes (beginning with not using birth control that one time). You will no doubt continue fucking up, too, until they move out of the house at 35.
The mistakes we make with our teenagers are different than the ones we make with little kids. They’re not worse, necessarily, but now your kid will notice and never shut up about it. So avoid these common and devastating screw-ups, and your child will have nothing to talk about in therapy. Except all the other mistakes you made.
