MUMS-to-be travelling by Tube can get a baby on board badge so passengers know they may need to sit down.

The badges, available from Transport for London (TfL), overcome the awkwardness often felt by pregnant women of having to ask someone to give up their seat.

It also means passengers in priority seats can see when they should give up their place.

Research undertaken before the scheme was launched showed that pregnant women often felt awkward or uncomfortable having to ask if they could sit
down.

And while some people said they were happy to offer their seats to expectant mums, they felt embarrassed if their offer was rejected.
