I didn't do it that way
Not to say my way is right, but it is what worked.
I would put Cassius in for naps, and IMMEDIATELY take him out when he woke up, and WAIT outside until he did his business, and PRAISE like mad! Same for after meals, with a new puppy it is a good idea to take him out every hour, at least. The crate really just lets you have a little more control as far as housebreaking goes. Theoretically, a dog won't go where they sleep, this is not to say there won't be accidents along the way. PATIENCE and PRAISE for going out side.. If you are going to be around for that first week, I think as long as you can keep close watch on your baby, you don't have to confine him constantly.. Good rule of thumb is that pups can hoold it 1 hour per age in months plus one,(correct me if I am wrong) So Cassius is about 4 months now, he could probably hold it 5 hours, though he is never crated more than 4. If your baby is 8 weeks, then 3 hours is MAX..
It is frustrating at times, just remember it gets better everyday!
Good Luck
