Free Baby on Board BadgeOrder your Baby on Board Badge here. Travelling on the Tube can be tricky for mums-to-be, but having a Baby on board badge makes it easier by letting other passengers know that you have a very good reason to need a seat. The Baby on Board badge aims to combat any awkwardness you may feel when asking someone to give up their seat. It also lets customers know when they should offer their seat. Badges can be delivered to any address within the Greater London area, and South East England.
