See! You probably could have used them immediately! :LOL My nb was 8#7 at birth. I've decided that's big enough.
We actually got them in the mail the week he hit 10#. I plan to seriously get my money's worth out of these.
My toddler can even wear them in a pinch, and he's 40#. I'm getting 2 more as soon as Caryn gets back to work.
