My situation was different from yours ,I was on entrepreneurship and my hubby was a dependant who works full time and for some issues we had to switch to flr fp.
My first child born outside the country qualified for the 7yr rule but the 2nd child born here was 6days short.
We were refused and told our child could return with us as a family ,we appealed using a lawyer who prepared our bundle letters etc and we did our witness statement .
At the court the home office person only asked if I had originally come here to stay ,family I have here,where I lived before coming to the Uk ,jobs I did before coming ,if I had any savings,but the first thing the judge asked the home office representative was if the children were qualifying children and he said yes so it was the reasonableness of removal that was at stake and our appeal was approved Thank God with lots of prayer added
I think your children would be seen as qualifying by the time the appeal comes round
