My Preschooler Is Out of Control

Published : Dec 01, 2025

“My preschooler is out of control. he is 3.5 years old and won’t stop fighting with his older brother (5 years old) including punching, hitting, and kicking without provocation that I can see. It’s also started to become public meltdowns where he’ll lose his mind over nothing and I have to peel him off of the pavement and dodge his little fists as he screams so hard he stops breathing right. He’salways been so sweet, but not anymore. What on earth can I do? The doc says there’s nothing actually physically wrong and now my other kids and pets are starting to give him a wide bearth, I just feel like I’m failing.” 

Upset child sitting on bench crying with greenery in the background.

I would like to start thinking about you first: You are not failing. When our child shows difficult behaviours, it is easy to think that we are failing as parents but that is not it. You are doing the best you can with the tools you have. Try to let go of your guilt. As parents we all go through challenging periods.  

Now let’s think about your child: 

  • You mention he is displaying this challenging behaviour at home. What about nursery or preschool? Is he displaying similar behaviour? Talk to his teacher to find out if you have not done so.  
  • Has something happened in his life? Have you gone through a divorce, have you moved homes, or had a new baby? 
  • If your child is behaving this way at home and at nursery, it could suggest that he is having trouble regulating his emotions. This is something very common for children his age.  
  • Whenever he hits his older brother gently tell him: “No, you cannot hit/scream/bite”. Tell him every time he behaves that way.  
  • Whenever he throws a tantrum wait for it to pass. Do not give in to whatever it is he wants because if you reinforce his behaviour, he will do it again. I know it can be incredibly difficult to watch your child scream and kick but it the best thing to do. Stay close, make sure he is safe, and wait it out. It is useless trying to reason with him once the tantrum has started because he cannot reason.  
  • Keep these strategies and be consistent. Consistency is key.  
  • It is likely that as your toddler gets better at speaking, he will no longer have the need to behave aggressively. Sometimes, toddlers behave aggressively because they get frustrated when they cannot convey their feelings and thoughts to us.   
  • Praise him. Children like to please their parents, so whenever he does something good, praise him and smile at him: “Look how well you have shared with your brother”; “You have helped me so much today”.  
  • Establish a consistent routine so your child knows when it is time to go to bed, have a bath, eat, and play. Children need clear boundaries and routines because it brings them security and stability.  
  • Finally, always remember your child is not bad or aggressive. It is only that sometimes he behaves aggressively.  

I hope these strategies work. Do get in touch with me if you want to discuss if further.  

I wish you all the very best.

This is ethically wrong and I don't think it's worth the damage it will ultimately cause to the relationship. And the issues it will cause for the one being spied on. Just don't do it.

This is such a great writeup. I think too often we get caught in a rutt of trying to categorise everything. Our daily lives are kind of dictated by categories and labels, certainly in a digital world.

I'd imagine this is quite deteremental for a childs development in the long run as nothing stays the same forever, and we shouldn't really be making these categorisations, especially towards our children.

Just live life, sometimes you'll have to be the parent that's the shoulder to cry on. The week after you may have to raise your voice a little when everyone is in a rush and you're trying to get your children's shoes on.

Just balance it all out, don't be too self critical and pick up on what your child wants and needs.

Again, great writeup!

Dear Robert,
Thank you so much for your comment. I totally get what you mean. It is always difficult to have kids living with you, wanting to support them and their parents but at the same time not wanting to step in anyone's toes. If there's anything we can do to support you and your family, please do not hesitate to get in touch with us.

Great Article! I'm a retired FNP. Years ago I taught a STEP program to parents via family court cases. I now have a daughter and her man disciplining three children 4, 8, and 10. The 10 year old has ADHD and my personal diagnosis is she's also Oppositional/Defiant. I believe the OD came from harsh discipline. All they seem to do is punish and threaten physical punishment. They say positive reinforcement didn't work however they tried it for about 2 months and then went back to punishment. I can't reason with them as "they are the parents"!! is all I hear. They all live with me and have since the oldest was about 2. Sadly I can see the other 2 developing issues like anxiety and aggression as well. Trying to show them another side of adult supervision when I have them but frustrating.
