You and your baby have a same smiling face.
You and your baby have the same smiling face.
You and your baby have the same smiling faces.

Please let me know which one is correct.
Thank you.

Hello! For me number 3 is correct, because you are reffering to 2 people, that is why "smiling faces" is the best option.
However, if you want to emphasize the smile on their faces, then the second variant might work.
Not a teacher.

The second one. You are saying they have the same face.

I'd use the second too.
