You will have to go through a maze where you must find a baby. To get through this maze easily, just stick to right wall. You will end up in your house. Then, you will come to another maze that is not as difficult, but us easy to fall off of.
When you get to the blood trail in the dark, you can jump across to the end of the maze. Run to the end of the straight trail and at the first turn, jump across. You can now see the second door. Jump across again and you will be there.
