I was on a coach at 7.5 months pregnant and asked someone to let me sit down for a while (it was a long journey). He asked why and I said I was seven months along and he didn't believe me. Not the only one either. I was very very slim before I was pregnant (stupidly underweight in fact) but ate like a hog while pregnant. As a concequence, became quite porky in every direction and the bump didn't show until 8 months, and even then I could hold it in and wear something baggy and just look overweight.

The only thing is, when I laid down on my back, the flab flopped to the side and the bump stayed sticking up and became impossible to hide. This is a detail that might be useful, you never know.

Perhaps she might take up smoking or something in order to deflect people's suspicions? Perhaps too drastic, but maybe a cigarette here and there in front of someone who might reasonably suspect?
