I'm pretty confident that I'm not the only DAD who's having a hard time disciplining a toddler. It reminds me a lot of what my mom used to say to me when she attempted to punish me, "Haider, punishing you is like punishing my self...", I get it now, mom.
The challenge is being able to keep your cool and let calmer heads prevail, while trying to cleverly divert your toddler's attention as she throws her dinner on the floor because the plate interfered with her pony-tail.
In the moment, you want to scream, among many other emotions, but what you learn quickly, is that it doesn't work. In fact, if your child is like mine, she'll take that as an opportunity to scream and be louder than me. And the icing, she'll do something similar the following day and say, "don't scream, DADDY" as she seems my eyes turn red.
So, what I've learned is that the silent treatment is golden! If you're successful in keeping calm, and removing yourself, your child will understand that the magnitude of their poor behaviour is greater than anything else she's ever done, and boom: YOU WIN!
The downside to that, of course, is that any time you decide to raise your voice in the future, your child won't think it's significant, because you're still talking to her.
Keys to success: diversion, silence, and threats that are followed through on...they're smart, and will call your bluff!
