Fixed Miles, how many a week?

BringMeMyFix Just got childseat for fixed beater. Will be gearing down to about 65", running slightly wider (ie softer tyres) for his comfort, and cruising around a lot slower (15mph?), at least until he starts chanting "faster, faster!".

I expect I'll be redressing the balance though, when I get out on my own...

just wondering, how old is your little one? I really want to take my boy out, but he's only 5 months old. Not sure if he's quite ready yet.
