Stimulus money

I’m on social security disability and I do not file taxes nor did I ever did so I obviously didn’t claim my child on my taxes . I gotten the stimulus money in the past. Now the $1,400 is approved and i know I will also be getting it as well. My question is if anyone here knows, I recently had my first child February 4th. Will I be getting additional money for him since he’s obviously under the age of 17 years old.
