He's probably just feeling unsettled and insecure, and he's acting out as a way of taking control of his environment. Giving him choices about his environment may help him settle in, such as which blanket he wants on his bed, or which toy he wants out. Also giving him more options in regards to things like which snacks he wants or what show he watches if he has screen time can help him exert that control his craving too. Either way it's something that will happen slowly over time, I wish you the best
No experience yet, but I will be moving with a toddler and preschooler in the next few months. I do have experience staying at various locations (traveling to family for holidays and staying for an extended time). We bring familiar things with us, do our normal routines and that seems to help with the adjustments. Also, we talk about it ahead of time, during the travel and at the family members house. And normalize things being weird/different Maybe have your toddler create a special space in his room where he feels safe/warm or whatever he seems to need more of lately
We moved about 1000 miles over 3 days, and surprisingly, the only thing that really got messed up with our 2 ywar ild was sleep schedules. I imagine it depends on the kid's personality, but moving is a big change for anyone. I think if you focus on routine and whatever might be familiar, the kiddo should settle down soon enough.
We moved on Tuesday with our 2.5yr old and his behaviour is terrible at the moment. He shouts at us, doesn't do as he's asked and his new favourite word is no! Everything is "i don't want to" or "no, I don't like that" 🤦🏻♀️🤦🏻♀️. I'm sure it will settle soon enough though cause he is definitely happier here than our last house
