I brought my first yorkie home at 8 weeks old, Gigio sleep with me I did feed her very two hours made sure she had water and that was also all day because she had very low blood sugar. I like the idea of the crate with you in the bed. Petsmart has a bone with a sound of a heart beat or the baby store will have something simpler, would also take the furbaby out to a pee pad every time you let the furbaby out of the crate. having a furbaby this young, I think it needs to be feed very 2 hours. It like having a real baby. the night will go a little longer with the furbaby, so feeding will go longing. it take time.
good luck
