Taking a buggy on a packed commuter tube, bus or train is one of the most stressful things of being a parent in London.
Too big, and the unwieldy method of transporting your child (plus all the associated accoutrements) makes getting about a mission worthy of the A-Team — not to mention invoking the ire of your fellow passengers.
Too small, and it just won't handle the rough and tumble of the capital.
Now TfL wants to find out which buggy families think is the best, and is running a vote to settle the matter once and for all.
It's recruited a panel made up of leading parenting groups and organisations including Netmums, Mumderground and 4Children, to pull together a shortlist of the 10 buggies they considered best for use on public transport.
They looked at criteria such as: size; foldability; weight: comfort and manoeuvrability; and affordability and style.
The five most popular buggies will be celebrated as 'public transport friendly' and will be highlighted on the TfL website and across social media so that parents and other buggy users know which are the easiest to use.
Here's the shortlist. You can make your feelings known by voting on the TfL website. The poll runs for 28 days from 31 May.
