We need a way to get Madison out of the living room and into that room at the far left. She's a good mom; if we can get the baby to go that way, maybe she will too.
Hint 2
But the door is closed, and the baby can't open it. We need to make Madison open the door first.
Hint 3
As Joey, go into the living room and blow on the thermostat. This makes the heat comes on, and Madison opens the door to cool things off.
Hint 4
Now click on the baby to make him follow you, then walk through the open door; Madison follows you.
Hint 5
Quickly, before they all get bored and come back, switch to Rosa and leave.
