Dear N.,
There's no problem here except what feels hard to you. It's really fine for a child in the terrible twos to act like he's in the terrible twos. And it's fine for the child to be happy when in the discipline place and even to put himself there. It's impossible for a two-year-old to turn on a particular mood--somber--just because we think it's appropriate. Grown-ups can't do it either, we just pretend. The best time-out system I've heard of involves putting the child there for the number of minutes that correspond to his or her age--so that's a grand two minutes for a two-year-old. Also, the time-out minutes begin when the child is quiet and reasonable still. Time-outs can help but they only do so much and a parent can only want so much from them.
If you completely accept that it's okay for a two-year-old to throw tantrums, and if you accept that your two-year-old may be on the drastic end of the tantrum spectrum (some of us tantrum more than others--that's life), then all you need to have in place are coping mechanisms for yourself. It's always (I do mean always) pointless to talk to a child throwing a fit. He just can't hear you then. Also, reasoning abilities don't kick in till age seven or so, so there's truly no reason EVER to give a two-year-old more than a few simple words of explanation, and that's only when he or she is able to listen. Even grown-ups can't listen when we're having meltdowns or rage attacks.
All you need to do (besides come to acceptance) is be there for your child. There's no need to behave like they've been bad or to be punitive. (That's why it's fine if he puts himself in the punishment spot and giggles there. There's no problem, then, and it sounds like in that moment he's not being bad.) If you can, it's great to simply be with your two-year-old while he's having a fit. Physically remove him (gently, firmly) from any stimulation and just be with him. Don't talk to him, don't put on smiles, but don't put on frowns or scolding looks, tones, or gestures either. Just hold him or lie next to him and be present while he calms down. If he can or does look into your eyes, hold his gaze without putting anything into your eyes. Just look at him to see him and love him. There's so much power in making that connection--again, if he's able. And if he's having a royal fit and you lie down with him and hold him down if that's needed for safety, he will eventually calm down and possibly go to sleep. And if you are simply a calm, steady, nonjudgmental presence, he will absorb that. He also won't decide he's bad, because you won't be telling him he is. Children aren't naughty. They are sometimes out of control. If you're in control of yourself and able to be with him calmly, that's all he needs.
If you have thoughts in your way--ideas that keep you from feeling calm--you may want to learn how to question your thoughts. You can read Loving What Is by Byron Katie, or go to her website (www.TheWork.com) and call the hotline. It's a free service; you just have to pay for the phone call. The person you call will take you through some simple questions so you can look at whether you even believe what you're thinking. All our thoughts that are unquestioned keep us from peace: I'm a bad mother if he has such huge tantrums; I really need to be doing something else right now; This is too hard; I hate him when he's this way--whatever it is. They're all just thoughts, and when we question them we clear the way for calm and kindness to come in.
That's all our children need. They will go through their lives and have tantrums and do things that we think are unkind, disgusting, inappropriate, and so on. It's all just growing up. We can be with them in peace or at war, and one of those keeps us connected and the other divides us and creates a lot of misery for all.
You're fine and your son is fine. It's so amazing that you're choosing to be a stay-at-home mom so young. How courageous of you! Sometimes it takes so much letting go. When they're having a terrible time in the terrible two, you can just make it your job to not be terrible yourself. To be calm and be loving to him and to yourself. Don't tell yourself you've done or are doing a bad job and don't hate yourself for your imperfect moments. Then loving him, no matter what he does, is a cinch. Just be with him and stay calm. He will benefit hugely from being able to trust in your solidity when he knows he has no control over himself.
And don't forget that a no is a no, so choose carefully when you say it. Talk less with small children. They need and respond to very few instructions and explanations. If you've said, we're leaving after we put these blocks away, you need to put the blocks away then carry the child out the door, even if kicking and screaming. Believe me, if your word is good, the kicking and screaming will pass much more quickly. If the child knows you're going to spend half-an-hour saying "We're leaving in five minutes," and "Okay, one more time," when you've said that five times already, then you're creating a kid who will throw fine tantrums. It's not his fault--he just knows you don't mean what you say and of course he will try to get what he wants. When the parent means what he or she says, the child understands. And I'm not saying to override your child all the time. When there's choice, give him the choice. But that mostly comes later. At two, there's time: it's time to go. It's time to eat. It's time for bed. They get that, especially if you follow through. Even for what foods you offer and what clothes you offer, it's easier at young ages to simply offer one thing. If you're feeling expansive, go for two: you may have this or this. If you go into more than that, the child can't keep up. Little kids aren't equipped for a lot of choosing. You can simplify things for both of you and help yourself to stay calm and solid that way.
I hope these things help. You're amazing. Love, Jaya
