Slowed down baby laughter and tears

We  are a little bit early for Halloween but I thought I would share these  with you. The spooky consequences of slowing down or shifting the pitch  of babies laughter and tears until they sound a bit like adults. The  results are unsettling to say the least. First off a friend found a pitch adjusted version of a baby crying.

You do the same with slowly laughing baby.

Worringly, it sounds a bit like sobbing too. Which is interesting in  itself since laughter and tears are the first communicative sounds that  babies can make.   However, when slowed down a little less baby laughter sounds  surprisingly normal.
The original full speed version is here.
I think they sound a lot like legendary British comedian Sid James
