I don't know where this comes from..."the terrible 2's"....it's 3 that gets hectic! At 3, kids now have the mobility and the thought process to start putting into action all those things they were just considering at 2. All 3 of my boys were more of a handful at 3 that at 2. Love 2. Live 2. Hug and cherish 2. Buy aspirin for 3!
While it may seem terrible for the parents (yep, I have one of those right now ) it is just curiosity, and a desire to know where the boundaries are. Kids will keep pushing to make sure where the limits are and how firm they are, and what kind of actions might affect whether or not they get what they want. Guidance during this time can go a long way to making the future years better for both parents and kids .
