How To Deal: Kids that throw tantrums

I admit, I have a lot to learn about motherhood and parenting. I've gone a long, long way from that 22-year-old young mom who can't even carry a small baby without wincing before she settles into breastfeeding position but I am so so sooooooooo far from being a perfect mom. There's always a lot to learn, especially when you're trying to raise a child so I am opening an avenue for moms to share their thoughts, tips, and tricks on some parenting issues that we all have.

I want to kick this section of the blog off by asking this question:

How do you deal with your kids when they throw tantrums?

I see a lot of kids throwing tantrums in public, most especially in toy stores. Even my precious Brianna has her moments. It usually gets annoyed stares from everyone else but a part of me thinks that these people don't know how hard it is to pacify a kid who seems to be on a crying spree.

My approach to this is to talk to Brianna beforehand. Let's say we're going to the toy store. A conversation like this usually takes place while I give her a bath.

Me: Honey, we're going to Toy Kingdom later ah pero we're not buying any toys.
Brianna: Okay Mommy. Pwede play?
Me: Play lang pwede.

When we get to the mall, I remind her constantly - like, every 10 minutes. If my mom did that to me, I would've lost my mind - that we're not there to buy toys and usually that does it for her.

Now, if that doesn't work, I give her a timeout. When we're at home, it's usually in a corner. When we're out, I carry her and whisper things to her like how it's not something she should be crying about, etc.

I'm pretty lucky that's all it takes for her to calm down - well, that, and the tiger look which I swear, scares the beejesus out of her - but I would want to know how other parents do it so maybe I can tweak my approach a bit for it to be more effective...or so that I can prevent it to happen altogether.
