Need some padding idea for this bed gap.
Ok so my nephew has this wooden bed next door that constantly makes noise when he's in it. The bad taps the wood on the wall (it's the same on both ends). I've tried shoving things in between but they all eventually fall. There is a large hollow part behind the back board which makes it harder to stuff something since it's not just flat solid wood. Any tips or advice (can't glue or do anything permanent since it's his bed) to muffle this or block the movement between the 2 spots would be grateful.
