1. Take training wheels (offence against the trades descritpion act [UK reference]) - they train nowt'
2. take pedals off
3. lower saddle so she can rech ground easily
4. get her to "walk" the bike along (plenty of videos on youtube (see balance bikes))
5. find a grassy slope leading to flat ground so that she can get a bit of speed up
6. when she can propel herself fast enough to keep her feet off the ground for a few yards, get her to count out loud (with you) how many seconds (roughly) she can balance without putting herfeet down
7. when she's up to 20, put pedals on, teach her the "pedal up/power pedal/pedal ready position, help her get going with gentle push on her back - not the bike - and your troubles will then begin
8. get her an Islabike - resale value is fantastic
