Let me guess....U R a mom, huh?
If not (and you're the pops)...plz 4give me. If so, Girl, been there!
Kids have the worse sense of humor....or is it that we adults lack it? IDK, all I know is that I've learned from my husband to check my responses. Basically, if a kid likes to hear your voice get all Mickey Mousey (as mine do when I'm mad or frustrated), or your nose flare as your face turns purple and your jugular throbs...Best believe, they'd want to see it again & again (esp if you're not the "disciplinarian" in the home).
Sure, I discipline our kids, but my husband seems to be more effective....I think it's the stern look & deep masculine voice he has cuz I've tried it (well, tried to imitate him by deepening my voice) and it alone gets me more results, though physically it's painful for me to do regularly....& we all know how short our little one's attention spans can be. LOL
Really though, keep your emotions intact. Never let them know what your thinking, or if you're angry/frustrated/scared etc. <I've a fear of spiders & most insects, & have learned very quickly that my son will happily present something gross to me whether dead or alive should he get a response of terror> So, if you display such emotions in any matter that may be mistaken as comedic to the easily amused, I assure you, that in such incidences that you find your 4 y/o involved in, if you respond stern, yet without any exciting emotions, she'll get the point & it would be made clear if it's followed by some type of discipline that is tangible. ---The lock her out & eat her favorite icecream deal, doesn't sound bad at all.....Or you can make her sit in the corner as you watch her favorite show or have her sibling(s) play with her favorite toy or game.
