My 19 month old just started doing this... I guess, I was spared a few months of it - thank God.
Since, my sweet Lilly June is just perfect and there is no excuse (like medical issues) that would cause me to go through bleeding heart compassion and understanding over her fits of rage, and coddle her, I am just enjoying treating her like I would any other toddler that performs such a display of twisted beauty.
She looks me in the eye as she strikes. I usually grab her arm mid swing. It's important to catch them "in the moment" and besides we have to stop them from hurting someone (even though it doesn't really hurt when they hit us). I maintain the eye contact when I stop her in the moment. I usually furrow my brow to make a cross and disapproving facial expression. And I say, "Angry, you are angry. No hitting (or whatever)", then I turn her body away from me and place her on the ground face down on all fours. I do it gently but in a firm, sturn, way. Then, I either walk away or resume what I was doing. She twists, turns, arches her back, whines, cries, hits the carpet some more, blows bubbles from her lips (spitting), and then sometimes stands up to come at me again. I just do the same swift, quick disapproval, and I give her the social punishment of turning her away from me to tantrum.
If you are not in a place where the break dancing on the floor is appropriate, you can just close your eyes instantly and turn your face away from her as you hold onto her arms (only to hold them back from swinging again and again). The social punishment of cutting off eye contact is usually the most heart breaking to them at this age. Because they are dependent upon checking in with Mommy's eyes to see if we are paying attention, happy, approachable, relaxed, scared for them, etc. They might not talk much at this age, but in their quietness, they have observed us in their gaze since the day they were born. Our eyes are like a wellness temperature gage to them.
Try this and see if it works.
And one tip to the moms who have toddlers that bug them frequently, keep aware of your facial expression as your annoying, interrupting, "up in your face" all the time, toddler (pre-schooler) approaches you. Although you just might want them to leave you alone for just one second to complete a thought of your own, just take a moment. Before you look at them with eyes bugging out like as if you are a crazy lady. Or before you look at them with furrowed brow and an expression that clearly says, "what the blankity blank do you want now". Or before you roll your eyes. Just take a moment to close them for a second of regrouping, take a deep breathe, relax your facial expression - I even purposely raise my eyebrows a little and smile just to put on an attitude of approachability and patients. I look them in the eyes with kindness and love the majority of the time, even when I'm feeling extremely angry and irritated inside. And most often I come down to their level. I spend so much time on my knees.
That's one way to show them how to manage anger. Anger is the result of feeling violated, frustrated, or unable to communicate an unmet need. Aside from the times that we are imperfect humans also, we can show them this kind of anger management of "an attitude adjustment". And that is just what the change in facial expression does. They wont understand as toddlers, but you will see it when they are teenagers. When my teenage daughter is really irritated with me, she will put on her happy face (although her teethe look like they could crack under the pressure of the clench) and in a sqwealy voice, she'll quietly scream "whatever you say -mom-". Hey, she's trying to be half way pleasent. And I think she knows that our family (in general) doesn't operate in a way where we go all about exploding our anger on each other. Her biting the tongue, clenched teethe, smile technique sends the message to me really clear that she disagrees with me, but she's showing restraint. Kind of funny actually. And boy oh boy was she a big tantrumer of the overt kind and the sneaky kind. She was a genious at destroying her room -on purpose.
Don't you just kind of smile inside when they flip around like some big strong brute swinging all over the place at this age. I still feel the same way when my teenager does her little smiley fits. I think it's kind of cute.
It really is hard for me to not feed into Lilly's tantruming. I really would love to stand back and watch her bust a move. Maybe, even add in, "Wow, that was a good flip over, hand slapping, flopperoony. Look at you go girl." Of all the things, this is hard for me to restrain. I just have to walk away or I end up enjoying it too much.
