I'll be 30 in July.
It's funny how age is perceived differently depending on your location - when I had DD I was a week off turning 24, and I was considered a "young mum" by the hospital staff. She was born in Sydney.
Now I'm on the Central Coast, and I had my DS almost 10 weeks ago, and was referred to a few times as an "older mother".. (there is quite a high teen mum population). I've never been just a regular aged mum!
