Thinking ahead here for when my son can sit up and come on the bike with me. I'd really like a front-mounted seat, something like this. Does anyone use anything similar? Also, when did you start putting your little ones in them? Our son is quite chunky (coming up 17 weeks and 16lb something) so will soon be at the 20lb stage the above seat requires, but presumably he needs to be able to sit up properly first?
Thanks!
