Can you avoid tantrums?

After reading books on managing tantrums in toddlers and kids, coupled with some experience, I thought that tantrums for my twins could be minimised. But today, I learn that some tantrums are rather difficult to avoid.

Asher thrown his tantrums over a 'minor' incident after he came back from the childcare centre. I immediately knew that he did not nap well in the centre and will continue with the tantrums until he sleeps. That is the issue here. If you send your kids to a childcare centre, you could not have control over the causes of the tantrums, which is lack of sleep here for Asher.

So what should you do then if you could not "remove" the cause or causes of the tantrums? Distraction? Yeah, work most times but for a short time frame. So got to keep your cool till the kid settles his 'mood'. But most times, it is easier said than done, and I just lose some of my cool earlier.
