My 20mo fell out of his cot bed last night, loud thud on floor at 1am poor lamb. We had to drop the cot sides many months ago as he's quite the climber. We've put a Lindam safety guard on and usually he's okay. But he does have a tendency to sleep horizontal across the bed and with his head quite close to the opening (beyond the safety guard) so I guess that's what happened. Do I need some kind of 'crash mat'? There's carpet and a rug but I'm not happy that there was still quite a thud. Any recommendations would be welcome. Thank you x
