Maybe Baby by MadamPuddifoot9
When his staff informs him that a warlock baby has been abandoned on the steps of the Institute, Alec feels an instant connection. Magnus is a little apprehensive because he never thought he would ever have the opportunity to be a father. Now that the blue bundle of joy is here, Magnus and Alec must decide if they're ready to take the next step.
This is another delightful family-oriented story in which we see Malec grow from power couple to power co-parents. My heart melted reading about Magnus and Alec's interactions with little Max, and I'm positive you'll fall in love with this story as well. Check it out!
