If you are going to crate her during the night at this young age..you'll need to set your alarm and get up every 2 hours. They just can't hold it that long at that age..just think, her bladder is the size of a pea right now.
Sleepless nights? Yup..that's the name of the game being a new puppy mom. Just make yourself get thru it and it will pay off for you in the end. I promise. Yes, you will live on coffee and red bull for a couple of weeks, but your reward will be priceless. And, you will finally get your DESERVED sleep
(if you can't take her out every 2 hours, do NOT crate her...this will just teach her to be ok with laying in her own pee and poo)
