Toren already does the opposite of what he’s told

Toren started jumping (both feet at the same time) earlier than most kids.  I tried to catch it on film but when I asked him to jump, he wouldn’t.  I finally decided to try reverse psychology on my 22-month old son.  I told him, “Don’t jump!”  Et voila:

I’m not sure what this means.  A few weeks later Toren wouldn’t give me a kiss goodnight.  I told him not to kiss me, and he wouldn’t stop kissing me.  We’re in trouble… 😐
