Eveyone has finally turned 1 year! And now I am letting the crate doors remain open at night (they are located in our bedroom) & putting the baby gate across the bedroom door. Sometimes they sleep in their crates, but more & more they are joining us in bed. My main concern is that they burrow under the sheets. I'm afraid they will suffocate! What do you thinkFunny thing is they have a cuddle sac & could care less about burrowing, it's just in bed with me!
