Hello,
Sure that could be the reason he is acting out. But the reality is people need to work, so you need to find a place where your child is nurtured and above all feels safe. I am a waldorf teacher and some waldorf sites might give you some support. Here is one of many links to give you an idea of what I am talking about

These things I'm going to list sound trivial, but believe me I have witnessed changes in children over and over again. It is really just common sense.
In the early years, waldorf theory stresses four things:
1. Warmth. Keep your child well dressed in layers. A child does not have the capacity to really tell is they are cold until they are about 10 years old! When they are young and underdressed they have to use vital life forces to stay warm. So keep them very cozy.
2. Rythmn (or routine). Very important, keep a regular schedule and routine as much as you can, the child will have a deepened sense of security. Meals, bedtimes, have a regular routine. And and EARLY bedtime. My 7 year old is in bed almost every night by 7:30, and he is ready for sleep ny that time. Before I tried it I never would have believed it, he always went to bed around 9:00, then I started putting him to bed at 7:30 as his teacher suggested and he went for it. Now I actually have some time in the evening for myself (or the dishes).
3. Chores. When your child is a bit older, helping around the house makes them feel important and included. Young children can feed pets and help fold laundry are two ideas.
4. No media. Don't freak out, that is right no media. No movies, tv, cell phones, you tube, or internet until they are older. Media can really mess with our children's pliable and incredible brains, belive me I am a teacher I see it everyday. They will have enough media when they are older, but when they are young protect them from it.
Anyways, I hope this hepls. Steps you take now will help your child be calm and strong for the future. One of my favorite parenting books is "You Are Your Child's First Teacher". I would suggest also finding a waldorf preschool in your area. They are trained to really nurture and love the children.
Remember too that you are the parent and have to be in charge. If you aren't streering the boat then no one is. Be loving, firm, and consistant. Some things are not negotiable, you just matter of factly say what is ok with no discussion. Your child will come to feel very safe with you and he/she will know just where they stand.
One last thingis, children until the age of 6-7 are learning most;ly by imitating, so you are the prime example of how to be a good person.
Hope this helps.
