i think under 22 is young... I think 23+is a more common age to start having kids.

I had Zach just after my 17th, bella when I was 19 and will be having my 3rd while im still 20. At 20, I still class myself as young but compared to all the mums in my Young mums groups and at the Young womens clinic... im not really that young anymore afterall lol
