We moved house a couple of weeks ago and my DD is struggling with the change. She is 2yo next week, doesn't go to nursery but my parents look after her 2 days a week when I'm at work and I try to take her to toddler classes/make play dates/go to play parks/play cafes every week so we have at least some time around other kids for the other 3 weekdays even if its just half an hour each day. She went through a timid spell with other kids a couple of months ago after a bad day at the park when another kid pushed her out the way etc basically normal kid stuff that she isn't used to. I made such an effort to help her interact with other children because of this and so she wouldn't be scared and her confidence really grew and it was so lovely to see her play alongside other kids.
Like I said we moved house a couple of weeks ago - my parents took DD for the day and we made sure to talk to her about what was happening. On the morning of the move she waved goodbye to our flat and said she was sad (heartbreaking!). Once we were all moved into the new house we hurried to get her room ready and for the living room to look a little like home and because my brother arrived to check the boiler etc I asked my parents to bring her to the new house. She seemed a bit bewildered but loved running around in the garden etc. My OH and I had the day off work the next day and we were all exhausted. DD tantrums skyrocketed - usually she is very good but was having meltdowns over the tiniest things. I assumed this was because of the move and she was processing it all. After a week she was slightly better and is slightly better every week (I think this is our 3rd week in the new house) but she is unbelievably clingy with me - won't let anyone else help her, not even her Dad who she is so close to (he's been WFH since the start of the pandemic). Whenever we go out anywhere she wants constant physical contact. When i take her to toddler groups she runs away in fear from the other kids. We've had a few play dates and has been fine with 1 on 1 with other kids. She also has a real problem with going in the car now - I know no toddler likes going in the car but this had been a huge change that's happened suddenly. She also hates leaving the house now which is so unlike her - she loves being out and about. Her sleep has also suffered - she usually sleeps though the night but has woken up on a number of occasions crying and her sleep has been very disturbed- lots of tossing and turning.
Basically my question is how do I help her to feel more secure? We spend lots of 1 on 1 time etc. My mum mentioned the other day about how much more she must feel the moved because she was 4mo when we went into lockdown and our flat was all she ever knew before we moved. We have gone on holiday and she has always settled into the airbnb fine with no problems so I thought the new house wouldn't be too much of an issue...
