Oh God, mine destroys everything she can get her hands on... I blame it on her being too smart for her own good and needing the extra stimulation. It's frustrating, and messy (especially when she decides to trash the contents of the fridge! I must have cleaned up four smashed eggs yesterday!), but for the most part I just let her go at it because it's not like she's being malicious about it... just exploring, trying to do things for herself, mimicking what she sees DH and I doing every day (eg climbing on the kitchen bench and flicking the kettle on to make 'Emmy cuppa caw-fee? Me lub a caw-fee')... sure, she has her moments when we say 'no' and she glares at us and proceeds to commit mischief, but again, I don't think she really means to be such a monster, it's *that age* and pushing boundaries is part and parcel, or so I'm told...
