She had a Puky Balance Bike for 18 months.
She certainly didn't ride it constantly as she shared it with her brother and also has a scooter which she rides a lot - but even so, she is able to ride the bike she got for her birthday on Saturady already!
I am very proud of her, and also really pleased that the balance bike 'worked' IYSWIM.
So anyone considering a Balance Bike for their DC should definately get one I say!
