it shouldn't be hard to imagine a child soldier program. Maybe one created by Cerebus as an elite corps of grunts born and built for the oncoming Reaper onslaught
In the lore books, Revelation, Ascension and Retribution, there is a child biotic training program created by the Alliance, and basically funded by Cerberus in hopes to advance human biotics and research of implants. I know its not in the game, but it would be nice to see something about it, seeing how it was what Capt. Anderson was doing between the games, dicking around with Cerberus, the lead character in the books and in the third book, Aria T'Loak.
Edit. So it makes up a lot of the events between the games and helps fill you in. The first book however was a prequel to ME1 and tells you how Saren discovered Sovereign, betrayed the council and that whole fauxpas about Anderson being the "first" human SPECTRE and fcking it up.
