Aged 3, 1, few weeks, and 2.
I started late, and then couldn't stop.
In slightly different order. Was aged 1, Was aged 2, Was aged 3 and new born.
Eldest has two sons, third daughter on the left has grand daughter.
All four went to university. One has never left. And another just heard today she has an unconditional offer to do an MA.
At least we aren't funding it any more!
