My wonderful babyboy has decided to bring on a new habit. He is digging up the rug by the bedroom door. He has ripped up all of the padding underneath the carpet in the hallway and will not stop ripping it up. He has been shown what he has done and been told no. He has been put outside for "time out," but he keeps going back for more. The problem is we can't put him in a crate b/c he hurts himself in it and he's been left in the house alone plenty of times, but all of a sudden, he's starting to chew the carpet up. Anyone have any suggestions?
