Yeah, it's both in this case and not either or as far as weight/age, so he needs to be 12 months *and* at least 20 pounds. I think, if I remember correctly, that they are actually recommending 24 months now instead of 12 but I think legally it's still 12 (and you can use a rear facing convertible seat if the infant seat is getting tight for him. The convertible we have can be used for 5-60 pounds both rear and forward facing. HTH!
