Sweetheart, you have my sympathies. My eldest was exactly the same, now his little brother - at 18 months - is trying exactly the same thing on. Yes, it IS a boundary thing. Apparently, this happens particularly with boys more than girls - I can't remember where I heard it, but apparently young boys get sudden surges of testosterone which make them want independence, and to - essentially - 'fight' you. They are trying to grow up, to find out where they fit into the adult world (think of cubs playing at catching prey), but these urges are more advanced than their actual mental capabilities for reasoning, so you get strops, tantrums, violence, aggressive behaviour. They are looking for a reaction, a way of learning what is OK, and what isn't.
I'm not a great fan of Super Nanny, I must admit. Whilst she seems like a lovely woman, and an excellent nanny, one thing she is not is a parent. I think the whole thing gets so much more confusing, upsetting and frightening when you have a maternal or paternal bond with this shrieking banshee who is a billion miles away from the sweet little darling you brought home from hospital; and feelings of guilt and remorse for punishing a child - as a parent, my god, I sometimes wish you got a straitjacket in your Bounty pack.
I used a combination of approaches, really. First the 'trying to make something interesting', through bribery (yes, I know, I know!), to stern words, to ignoring, to then grabbing him by the wrist and dragging him kicking and screaming to where I needed him to be. And yes, I have smacked his bum a couple of times. It has been very effective, but I think its effectiveness comes from the fact that is an exceptionally rare occurence, and when he HAS had a smack, he has realised that what he had done was very, very, very bad indeed.
Fortunately, as they get older, they are more quickly engaged in something, so shopping CAN become more fun. A trip to the post office can become a hunt for insects at the roadside. When a sulk / strop / tantrum is about to ensue, just looking up and going 'Oh wow, look at that!' will stop a strop dead in its tracks, because they are so inquisitive they'll forget about their tantrum and be more interested in what they can't see.....
Another thing that worked well for me was the 'advance warning', so he would know in advance if, say, we would be leaving the park. I'd say 'OK, 5 more goes on the slide, then we go.....etc etc until OK, this IS your last go on the slide, then we leave'.
I also found that giving him 'freedom' helped. It's that testosterone thing again, he wanted to be the little big man, the mini Alpha male; so just letting him outside in the back garden to play (obviously it was safe), or letting him play upstairs in his room without supervision, or wander off (within reason and, again, only where there was no threat of deep ditches, water etc) on country lanes - it was just enough slack to let him fulfill those desires to be his own person, and he seemed much calmer for it.
He's 4 now, and we still get the odd tantrum, of course we do; but this 'little big man' act has developed so beautifully - he is my protector, now - 'It's OK, Mammy, I'll look after you', 'Don't be scared Mammy, I'm here!'; and he is my helper - he is so keen to help out. He unloads the washing machine, gets things out of the fridge for me, sets the table, makes his bed, bless him. Again, he feels 'grown up' doing these big boy things.
Don't worry too much, this IS very much a phase. Show me a mother whose child has never had their horrid moments, and I'll show you a liar. Or at least someone with a very bad memory.
Remind me of this post when I am tearing my hair out over his brother, won't you? An 18 month ball of horror at the moment. Wants all the same freedoms, but also wants to do everything his 4 year old brother does. And my GOD does he let you know about it when he's not happy!
Happy days, eh?
