I don’t think so. I’m pretty sure that crying comes from a different part of the brain. I have no idea where I got this notion. “The Simpsons”, probably.
I was talking (not argueing) with a new dad at work the other day, and he say’s crying is language. I asked him if his new son cries in hungarian (his native language). He said “sure”. 
Typical dad.

Well, crying is a language because it communicates desires from baby to Mumsy. I’m not sure which bits of the brain it uses, or if Junior’s talking about me behind my back, but crying is a form of communication. If you count tweeting, barking and peeing all over fine upholstery as ‘language’, then so is crying - it depends on your definition of ‘language’. But Babyish has nothing that can be called ‘dialect’ - it’s inborn, like the walking reflex. I’m sure Chinese Junior can get the point across with American Mommy without trouble - there’s not enough genetic variation in the human genome to make any serious differences in baby babble.
My first inclination was to say no but then I remembered all the different cries my Kiddo had when she was a baby.
There were noticible differences between her “pain” cry, “hungry” cry and “bored” cry. Actually, she still has differences in her cries at 3 1/2.
Maybe crying isn’t so much a language as it is an expression, like a smile or a frown.
Well ok, it is language. That’s very true.
What I should have said is that it’s instinctive, a survival reflex that’s from the caveperson part of the brain. I think the variations are learned, though. Babies quickly learn to use whatever gets them what they want, don’t they.
Babies frown? Awww

No, not a language.
To qualify, an animal must be able to creatively assemble pieces of meaning into a sentence that expresses their intent.
This is the whole argument about whether chimps have language: they use signs, but the detractors believe they just learn to make a particular motion in a particular situation.
Babies crying are communicating, but not using language.
