I'm 19 weeks pregnant with first child and not showing very much yet, unless I wear figure hugging clothes which I'm not used to doing. I wear the 'baby on board' badge on the tube (I'm usually travelling at rush hour) but more times than not I don't get offered a seat. I wore a tight top for a couple of days, to make the bump more obvious, and I noticed I was more readily offered a seat. Have others experienced this kind of thing? It is frustrating that - at least as far as my experience goes - the badge is often not enough and plenty of people need to satisfy themselves with seeing a visible bump before they think you deserve a seat.
