Palmer is generally a very well behaved child, apart from the odd tantrum and hitting.

When she does/touches something she isn't meant to, isn't safe for her or hits someone (she's never hit anyone except me and Kim) and we say "No!", she just laughs, every single time. And now when we do something she doesn't want, the little scamp says "NO!"

Any tips on getting her to understand?

It's not out of control, but I can see it becomming a problem as she get older.

If you say "Put it down" when she picks something up, most of the time she will.

She understands "Be Gentle"...but sometimes chooses to ignore it. Like with the cat, for example, who gives her a claw-free swipe as a warning. That works to deter her.

Just as I am typing this she has made a beeline for our vinyl collection and when Kim said "Palmer, No!" she turns around with a massive grin on her face.

She's a bright girl, has a good amoutn of words in her vocab, understands most things we say to her, but why does she be so defiant? I am clearly not up with the inner workings of the toddler mind!
