My toddler is 3.5 and she recently thinks it is hilarious to annoy the crap out of people. She will make messes, do naughty things, ignore everything we ask, spit on people, jump all over people all while cracking up. And no matter how big or non existent my reaction is, she will keep going because she knows its annoying. I havnt noticed this behavior from any other toddler, is this normal? Any suggestions to curb the behavior? ADHD runs in her dads side, but its just so hard to tell at this age.
