>>1066047do yourself a favor and get an osprey poco plus, and get them in it and used to it as soon as they're big enough. 16 lbs, iirc (i started mine early at around 4 months because he has a super strong neck from having an extra big ol' fucking lollipop head). they're spendy, but you can find them basically brand new on craigslist by retards who decided to wait til their kid was 18 months and they wouldn't tolerate it.
