Smashing things like the Hulk is only one of the problems I've rolled with as my kids pass through the wild toddler stage. Yes, it's a stage. Thankfully, your children will one day seem less like climbing, storming monsters and more like calm and cuddly cherubs. In the meantime, I recommend being firm but allowing your tot to satisfy curiosity and stretch those muscles. Of course, you should also be well versed in in first aid tips and procedures....just in case.
