Hey Emma
No I never swapped it cos when we went back to Toys R Us it turns out that the clicking is normal
We just didnt hear it in the shop cos its noisy with music etc! So had no real reason for them to let us swap it
So I have just turned the wheel so she cant pedal but at least it doesn't click (and when she is able to peddle I'll turn it back, cos it doesn't click when she pedals!)
So sorry nope we dont have instructions for timmy ... but they arent too tricky, hope you manage it!
