When we moved we made sure that the girls rooms were fully unpacked on the day, so they felt like it was home straight away. I also put them into daycare on the day of the move so they weren't in the way or stressed out by all the commotion.

Before they moved they helped pack up their toys so they knew they were coming.

Dd1 asked to go back to the old house a few times but she was 3.5, dd2 was the same as yours 22 months and was happy from the beginning.
