No, he's really not *that* big. I know that. He's about 13lbs, give or take, now.
And yes, I do know that the age/size ranges for baby clothes aren't really accurate. They usually were for Asa, who was and is a total peanut, but not for most kids.
Still, it's shocking when I put him in a size 3-month onesie for the first time, and have to pull it so far down in order to snap the crotch that he ends up with a low-cut neckline.
These pictures don't do it justice. He's not even three months, and in clothes that Asa didn't wear until quite a bit later. It's not so much a matter of comparison, as of resetting parental calibrations. In other words: a mind trip. (As though parenting weren't a big one already.)
