Backtracking a little here.
One of the major considerations with moving to another country was whether Jono would regress at all.
We decided that if we returned to Australia after 18 months, and he is the same as what he is now, that it was a risk we were willing to take, to give all the family the opportunity to live in another country.
For the first 4-5 months everyone settled in very nicely, and we established routines that worked, as well as having the chance to go exploring around a bit of the country.
We thought he was coping very well and we wouldn't have problems, he grew a little but no regression.
Then we hit a bumpy 2 weeks, reflecting now it wasn't an issue, but at the time we were fairly concerned.
He started to talk less, interact less, obey less, have less interest in us as a family and communicate a lot less overall. We spoke with the school if they noticed anything, but he was still too new for them to know him that well, and they had only noticed a few minor things.
Mind you, it took us around a week and a half to notice it ourselves, and once we started talking to the school and got some interaction going, he pretty much 'snapped' out of it. He started growing again, interacting again, and even talking more than before.
Perhaps it was 1 step back for 2 steps forward? Perhaps he just needed a break? Perhaps the impact of the life change had finally hit?
We really have no clue, but the fears of regression are now gone, even if (when) he does regress, he has shown us that he comes back stronger, and that a good thing for us to take note of for our own lives :)
