I'm bullet pointing as I'm "on the run"
* I second the security questions. If at all possible, post a schedule of both meals and activities
* Questions are a way to connect. Children the age of yours are just learning the art of give and take in converstation. They connect by asking you questions.
* Being taken away from bio parents at 6 months is still a severe disruption of an important bond. Even taken at birth can cause attachment disorders (not saying s/he has an attachment disorder, just stating what is known)
*your children have an extra need to have a present parent. Boundaries and setting expectations can help: "I will talk to you now for ten minutes and answer all your questions. After that I need to do xyz and need to concentrate on that, so can't talk to you. You'll need to find something else to do then. When I'm finished, at xx time, we can talk and cuddle/read a book/watch a programme together/ etc"
*high anxiety triggers are moving house (just happened and in the future for you guys), moving jobs (just happened), loss (I guess they left friends behind?) etc. This has been HARD for all of you. You need to look after yourself so you can look after them. Make space for you, so you have space for them
*lastly: Huge hugs. We can do hard things <3 And you are doing them well. Still praying for you all
