why not make the baby cart mobile?
since the baby respirator was not plugged into the wall, hence the battery, why didn't he find a cart and a wheelchair?
He could have put the respirator and monitor on the cart, the crank generator on the wheel chair, tied them together, and push the baby around to wherever he needs to go?
The whole running back to the room every 3 minutes for a freaking 90 minute movie was so gay.
