I'm 24 but look about 19, I get looks from time to time but you just learn to ignore them. I think more often than not people are simply curious not judging. My mum told me when I was a baby she was walking around the supermarket with me in the pram and some old lady came up for a stickybeak and shook her head and said 'how sad, you're so young' then walked off. Mum had me at 33!!
