Sounds reasonable to me, too. Yes, there will be times you need to keep her away from trouble when you can't supervise. As she gets older, you can train her to stay away when you are cooking (if that is your wish) rather than being underfoot, and hopefully you can begin to trust that she won't get into trouble while you are distracted. The problem is when people constantly use the crate instead of observation and teaching the dog what is acceptable. Pups cannot learn the rules of the house whilst confined to a crate!
