Hi... Did you guys consulted him before making this decision to switch your home? If not, try to find out if he believes you should have asked him or not. Changing homes can be a big matter to kids as they are in a growing age and they tend to be more sensitive to such things. He might have accumulated some emotions that are resulting in his changed behaviour. Also, he might actually be finding it difficult to adjust to this new social environment and may not feel like going back to the old one as well. Try to find out if everything is alright with him otherwise.
Next Steps
