Before anyone points it out yes I agree:
it is none of my business
I shouldn't let it bother me
If thats all I've got to moan about I should think myself lucky etc etc etc
...but is it just me that thinks if you little darling is still so little that there feet barely reach the pedals, the idea of actually pedalling is beyond them as walking is still proving a bit complicated, they have to be strapped in so they don't fall off etc etc etc then really that lovely tricycle you have spent good money on is actually just a second pushchair!
