Hi and welcome.
We homed Jasper after he'd chewed through two other homes in 9 months, the last of those resorted to confining him in a tiny kitchen and not even letting him in garden because he dug it up. Initially he chewed here - internet cables, tv aerial, the wall and anything he could get his teeth into. Like you I wondered what I'd done subjecting the family to this, thankfully my kids are older and old enough to put their stuff away but they still leave things sometimes.
It might be worth looking at diet - could be increasing hyper activity, also once he gets used to your routine and having something to do might calm him, together with general maturing perhaps look at one of the dog games books, things you can do at home without taking too long when you've got a young family too..
Jasper is now 2 1/2, he's my angel (most of the time) and those days of chewing the wrong things are behind us (he still runs off with socks though). Hang in there, she looks
you've just got to grit your teeth to find out what makes her tick.
