my son did fell off from playpen twice while playing. luckily i had stacked on pillows and soft playmat below so they cushioned his fall. as for falling off while sleeping my guess is ur son could be waking up in the middle of the night and might have stood up and toppled over. if he's able to climb over the side railing, chances are its easy to fall off. i dismantled the playpen when my boy reached one year plus after seeing him attemping to climb out many times. its getting too dangerous to allow him to sleep in there.Dear Mummies,
Im puzzled as i never heard that a toddler can fell off from playpen? Dear son (17mths) fell off from his playpen while sleeping last night and when i hear him crying, i quickly woke up from my sleep and didnt see him in his playpen and found him on the floor....
