Wow! Little Peep- you are just the size of a seseme seed or is it a raisin? It depends on the website, but all I know is that for being so small you sure are doing a lot of work in there. It's hard to believe that the beginnings of your brain, cardiovascular, nervous and reproductive systems are already underway. And Peep, your little heart is actually starting to beat! Keep working hard, Peep!
