Rickshaws for children

Want to do the school run but have a commitment to sustainability?  On my perambulation to work, I saw a mum bicycling with a covered, connected carriage to the rear.  Now, theoretically this could carry shopping but it has little plastic windows, so I imagine, as she was coming away from where a primary school is located, it was not long in carrying her own young children.  What a delightful way to travel, speeding up trudging along when they can barely stand up or having to hoist them onto one’s shoulders, though I personally would have a few reservations taking this ensemble onto a busy road.  I know kids would be fascinated by it - something new and interesting to clamber upon.  Cycling would also solve the issue of tummy (as opposed to yummy) mummies.  It even works in the terrible weather, where wind and rain mount such a fierce onslaught that it literally takes your breath away and any activity takes on an anaerobic hue (I was just in these howling conditions).  I suppose, as the sprogs grow up, walking and bussing would supersede this innovative approach to an intractable problem, yet I applaud the spirit behind it.
