Slightly off topic but my little one went on the Weeride at 1 and all the way up to 2 1/2 now sadly grown out of it
Helmet wise i bought her one from the local bike shop this one...
Big mistake as the pointed rear hit me in the chest every time she moved her head back, Eventually swapped it for a cheapo argos one with the rounded back, think it was about £7 ish
Good thing about the weeride though is you can interact with your child as you ride so that you can keep her interested in whats happening.
Ps if anyone is in the market for a good condition lightly used weeride seat let me know.
