I have a 9 week old that we are crate training as well. We are putting her in her crate for an hour or so for naps throughout the day and we are also feeding her in there as well. At night we took our breeders advice and placed a light sheet over top of the crate so she would begin to understand that it is bed time. She whined and howled like mad the first night but we stayed the course and did not let her out unless she had calmed down to which we would then remove her every 2 hours at night to go potty. The 2nd night was a little less whining and by the 4th night she had stopped whining all together when we put her in there and is now going about 4 to 5 hours between night time potty breaks which to me is odd but I am not going to complain. My wife has also been working with her on using a key word for her to know when it is time to go in her crate that she is picking up on as well and she will now go in there from time to time on her own to get away from the hustle and bustle of the house. We also have several of her toys in the crate to give her something to do. The key is to stay the course and while it is aggravating and you are losing sleep keep at it and she will he will eventually get the picture and calm down.
