I personally feel that this baby either has relation to the Yeagers or is the random-a** Eldian baby that gets all the Titan shifter powers.

1. Yeagers: This one is probably one of the most popular. The "dad" (yeah, let's call him that) looks like Grisha from the back. The baby looks like little Eren. Or, it could be Eren grown up with his own son. Here's what I've personally come up with and gathered from Reddit (yes, credit is given): About Grisha and Eren baby...
 * Case A: Grisha is the dad, Eren is the kid. Eren somehow managed to change fate.
 * Case B: A except Eren is dead, and that's Eren returning to heaven or something.
 * Case C: Eren : You're free, because daddy murdered everybody else! :) (/u/Zekes Coffee Co)
 * Case D: Handshake that was animated in an opening. (Idk where this even started)

we need to remember the fact of Eren never was a free one and Grisha knows about it from the beginning he is the one who gives to Eren the titan power so I don't see him say to Eren "you free" but it is still possible. Hence theories A and B. Eren was indeed never free -- he's constantly trying to break out of the boundaries that have been set for him, which kind of defines him as a character.

I've seen theories that Grisha was under the Attack Titan's will after receiving it (eye color change, very sudden personality change) instead of his own. This probably lead him to the strange comment of "my son is a chosen one" (around ch. 70, can't remember the exact wording) and injecting Eren with the serum in the first place. Perhaps Eren broke free of the adverse will and that's Grisha in paths? Dunno.
