Sorry everyone, this is very fake, you are foolish to think otherwise!!
Of course it's real. Watch the background instead of the baby
This is real just because i've seen babies do amazing things. they learn quickly and if you grow up in a family or culture where there's a lot of dancing you pick up what you see. I know for certain that babies can easily pick up things that occur around them constantly.
I think its fake
real
I think this is real. My sister used to dance like this when she was a baby. She was so good, she grew up to be a dancer.
Anybody's who ever had a kid or is around babies on a daily basis knows this kid cant be younger than 3. Babies don't even have a sense of rymth until 2. Notice how he's dancing in perfect time. I've seen plenty of toddler's dance, but nothing like that. Mom Probably just thought it would be fun to strap a diaper on him, and let him go to town on the table.
When I first saw this video I was not quite sure. I have been to Brazil and some of the young babies can Samba quite well (I think its in their genes). The only thing I find a bit strange about this baby is his professional facial expressions. It still looks real to me 
It's real as you can get using reverse green screen. Basicly you have handlers with green suits moving the baby around choreographing the baby along with the music. You don't see the handlers as they are wearing the green suits. But what REALLY gives it away if the slight indentations in the babys skin every so often. The same effect was used during the filming of Evian Water Skating Babies commercial.

It could be real. He is from Brazil. My bet is that there is a mom or dad over behind the camera shaking their groove thing, and this little guy is looking at them and copying what they're doing. I doubt that he remembered all of that choreopgraphy himself.
