HI, I have crate trained all mine
We just added a new babie who will be 7mths tomarrow , where do you have her crate located ? I always put them in my room with me for the first week or so, they get to know one voice, I shhh them when they start whinning or barking, he did this for the first 2 nights, now he is out in the living room with the rest of my crew
we are also very early riser, between 5-6
every morning, They get to know the routine quite fast
the main thing is not to give into them when there fussing
good luck, I hope you get some rest
