Does anyone know where we can get a really little cycle helmet? dd is 2.11 but has the head circumfrence of a 1 year old - 45cm. We tried a hat that went from 46cm today in Halfords and it just didn't fit at all, even with all of the pads it just slipped off her head side-ways. Any advice? The makes I have come across as possibilities are the 'Met Elfo infant' - the 'Giro Me 2 kids' and the 'nutcase little nutty kids helmet'. If anyone has successfully fit one of these on a little head it would be useful to know
