I practice attachment parenting, so I aim to teach DD correct behaviour without scolding her for doing what, initially, comes naturally. She's 16 months. However, I'm wondering how to demonstrate the difference between when the same thing is okay and when it's not, and at what point it's developmentally appropriate for them to comprehend?
For example, I've encouraged DD to knock down stacking cups when she was a baby, and now she seeks out knocking them down as soon as I start building them. That's fine if it's with me, but if that was another child's tower then my DD would seem like a little terror.
