Hi Amy,
I was told that tantrums happen for one of several reasons and this could also include why your child screams, he is frustrated in some way of his situation: tired, hungry, thirsty, or bored. I don't know what suggestions or directions he's protesting so it's hard to give more detailed suggestions, but you could try offering him choices. For instance, my daughter will sometimes throw herself on the floor and cry because I say no to another popsicle or she's asking for chocolate and I'm making lunch. I will walk over and calmly give her the option to sit in her chair while lunch is being made or she can go play in the living room. She ended up throwing her own option at me which was to pick her up.
I think the reason why the bed thing has been working is because he is being removed from the situation and is able to calm down so maybe if you don't want the bed being associated with the punnishment, it can just be his room so he can calm down. Let him know that when he calms down that you will be willing to discuss what is happening here.
Your son is trying to learn to communicate his wants and needs and is getting frustrated because he can't do so effectively. My daughter is going to be 3 and while they have gone down for the most part some days are worse than others. It's all helping your little one communicate what they are feeling and finding out what works best for that little one.
One thing I'm trying to do more is getting her to sit on my lap and then try to calm her down with my voice and then help her express herself. Is she tired? Is she hungry? Does she not feel enough attention from me? Yesterday, she told me she was upset because she feels she is not able to express herself and I told her that it was okay to cry, but it's not okay to throw herself or kick me (which happens when she is sitting in her chair and I in mine) in the process. Then I hugged her and rocked her for a bit and she was okay.
I also let her get a break from me today by dropping her off at my mom and dad's so she could get some one on one time with them, be exposed to new and different toys, and have a blast there. I'm a single working mom so she is away from me 50 hours a week at the sitters so sometimes I feel guilty about doing this, but not after today! She didn't want to come home at first! She didn't want me going home either though without her so I just stayed a little longer then put in my request again that it was time to go and she was ready too. We went to the store and did some brief shopping and no tantrum. Instead near the end when she asked me to pick her up, she let me know that she was tired so I told her that we would be going home.
So I definitely think asking your child questions and when you find out what makes him tick letting him know by saying, "you are tired" or "hungry" or "eat" even. My daughter never says she's hungry. She's use to me asking if she wants to eat so now she says "eat". I thought that was a simpler word to start out with and then we can work to hungry. But helping your child to verbalize what he's feeling and what is frustrating him will help reduce those tantrums. At least that has been my experience.
The other thing I think helps is I give her choices once in awhile. I would let her pick from two different movies or two different outfits. Now she has names for her movies like, "I want to watch the cow or the monkey" so she can verbalize if she wants to listen to a particular movie. I say listen because she really doesn't sit and watch anything. She plays with her back towards the TV, but a lot of the stuff I have is educational so it's helped her learn her body parts (mom and I filled in the gaps so that she knows more than the video covers), farm animals, items in the house, and now I have ones for colors, counting to 10, and the Alphabet.
When she protests about an outfit I plan to dress her in, I make up two and let her pick which one she wants to wear and that resolves that issue. It's very hard work so I generally take a couple of breaths and then speak calmly to my daughter. If I can't keep my composure because I'm tired or sick, then I let her know that I need to walk away for a bit and we'll be back when we've both calmed down. she will be in one room and I in the other. Eventually, she will calm down and play or she will come find me. When she does, we talk about what happened and I try to find out what made her tick.
So I guess Amy as you work through these issues, look at this as an opportunity to show your son how to express himself and communicate appropriately, but here is the hard part, with the example he should follow which is in a calm voice. I think that is the hard part is addressing the child in a calm voice when we want to have our own little tantrum. Good luck and I hope I helped some. I'm still figuring this all out myself as I do quite well with my daughter except in public, but getting better since receiving some more tips which I'm going to try out one tomorrow. I think I'm going to let my daughter carry her purse with some things in there so she can feel more like momma when she's shopping and when she gets tired of putting stuff in the cart, she has something to entertain herself with.
If my daughter still acts up, we are going to go to the restrooms to calm down. I'm just going to try different things until something works and one mom said she has two different kids and a different strategy for each of them so that's why this response is kind of lengthy. There is no one right way to deal with this.
