Baby (赤ちゃん Akachan) is a floating, infant-like monster first encountered in Chapter 3.
They are floating infant humanoids that appear to have the same size as Isaac. Their mouth is stained with blood.
Babies slowly float towards Isaac, occasionally shooting a single blood shot. They also have the ability to teleport to anywhere in the room, occasionally close to Isaac. They usually teleport after a shot. The only random element is the shooting, and they have no specific cue to indicate incoming attacks.

- They appear in the original game.
- Babies use the same death sounds as gooballs from the game World of Goo.
