Mia is still in her soft crate at night, she's 4 months now. But her crate is right on the bed... well it's more like a bag. She's happy, I can sleep without worrying she'll jump down or get rolled on, and potty training is still on track
Good luck and remember every furbaby and human Mommy are different so you need to do what works best for you. But keep puppys safety at top priority!
