PLEASE HELP, i'm at my wits end my very mobile 12 month old is constantly climbing onto the furniture which before now i had never minded as he'd just climb onto the sofa and sit but now he has progressed to clibing onto the arm of the sofa and balancing himself there or climbing onto the coffee table which he thinks is hilarious and when i get up to move him he ends up in hysterics. i have tried everything i can think of i've tried telling him off, removing him from the area, distracting him when he's on his way, and even ignoring him which has resulted in him falling a couple of times and even that hasn't taught him, short of removing all the furniture i'm lost anyone any ideas??
