I'm one of 6 kids but we were pretty spread out born in 1976, 1978, 1982, 1986, 1991, 1994. My parents have had kids in our primary school for the past 26 years, but my brother leaves it this year.
It'll be great for Zoe to have a little one close in age to her since Maddy and Meike are that bit older. We only had one bathroom in our house (and still do) which is an absolute nightmare!
