Hi
@Jilldrinkwater , sorry you are having this issue, it's hard when you don't get enough sleep and things impact on your relationship.
I agree with
@snowbunny , he is still very young and they all are so different. At least he lets you know he needs a wee! Is Oscar crated at night? If so do you cover it so that it's like a den and therefore darker?
Don't despair too much, stick at it, it'll come good in time! My Cassie is 3 this week, I can't believe how time has gone, and she is now the best companion I could wish for, you family have all that waiting at the end of all the puppy days

I've never done it, but perhaps it would be worth getting up before he whines for a wee, and gradually make this later? Hopefully someone else will be along with more advice.
