(CBS News) Two of my favorite things that little babies do are sleep and laugh. They are so peaceful and cute (and nicely quiet) sleeping, and there's not many better sounds than a baby giggling with glee. So a combo of both may be the most adorable thing around. And this is exactly what baby Antonio is doing in the above video posted on YouTube by Varga Mark. Check out this clip, which is sure to bring a smile to your Monday morning.
What's even better, is apparently he giggled on like this for about 10 minutes. What could he possibly be dreaming about that would make him so happy? A little Internet digging revealed that babies will laugh like this in their sleep from the time they are as young as 17 days old. But with their world limited to milk, moms and naps at that point, what could they find so hilarious? It's just one of those wonderful wonders of the world, I guess. And we'll take that kind of mystery any day, so smile on little nugget, smile on!
