Sherie, I'd never thought about doing that with the pillow under the matress! Although with Blake's ferrari bed I won't have to bother as it's made 'car' shaped so it's high up about 25cm above the matress around the head.

Kellee, we actually put the cot mattress at the side of the bed so when DD fell out of bed she had a soft landing. I think she only fell out twice though and that was months after and we'd already moved the mattress. Gotta say, it was funny when she fell cause we'd hear a bang, go running into her room and she'd be fast asleep on the floor! It wouldn't have disturbed her at all!
