Big Boy Bed

After B recently escaped (climbed/fell) out of his crib. We decided it was time for a different sleeping arrangement. We started him out just on his crib mattress on the floor, but he fell off and woke up just about every night. We then put him on a twin mattress/box springs on the floor. He stays in a little better because it is bigger with more room to move around while sleeping. We have, however found him in various corners of the room when we check on him at night and in the morning. We have also found him almost off the bed but still somehow asleep. This morning he was found in the bean bag snoozing away.
