Have completed the survey but wanted to add a small point:
Under ages of children, I have put 4 and 6. But I have twins aged 4 - there is nowhere on this survey (or any others that I've completed) to indicate multiples. So according to the survey I have 2 children, but I have 3...
I know it's splitting hairs, but it just feels weird not to be able to say I have two 4 year olds, don't know why. Just thought I'd mention it...
