“I found it disturbing that air pollution could already be impacting on my child before they were born.” —Rose, South London

When I was pregnant, I had regular carbon monoxide tests. This is because exposure to carbon monoxide can impact on the development of your unborn baby. A couple of times my reading was really high, and that of a smoker. Once the midwife had ruled out that it wasn't due to anything in the home and that I was a non-smoker, she asked if I’d walked up the high street. "Often readings are high if you've walked up the high street past the traffic", she remarked before also saying she was moving out of London to the countryside because of her son's asthma. I found it disturbing that air pollution could already be impacting on my child before they were born. Now when I walk with them in the pram, I avoid busy roads and try not to take them along main roads when there is school traffic.
