I am sorry you are having trouble with your boy.
There are several possibilities for his talking.
One is hearing loss. I know he is young but it can happen at any age (even from birth)
When a cat is hard of hearing he becomes more upset at night (like sundowners syndrome).
The cat is not totally deaf but his hearing is reduced and his own voice sounds so DIFFERENT to him he will go around howling so he can test the tonal quality of his voice much like hearing impaired humans speak loudly or nasal.
He is then very dependent on his human mommy.
There are several things you can do. Play a radio softly at night so he does not "hear" so much quiet. Leave a soft light on so he does not "see" so much darkness. Get some feliway plug ins as these will calm him down, he can get very anxious at night. You can get them at some pet supplies or http://www.catfaeries.com/
Feed him a canned food meal with turkey as it contains l-triptophan and is sleep inducing.
Get some foraging toys to keep him busy
Tire him out with a laser pointer or feather wand.
I hope this help you quiet him down so you can enjoy him.
Please let me know if you still have questions. I will always be here for you and your baby
Warmest best wishes,
