That’s totally normal! This is part of Montessori and floor beds in general. Your baby has freedom and independence to sleep where she wants. Try to not have as many toys/books accessible at night so it’s not overstimulating to keep her awake. But it sounds like she does great at putting herself to sleep! You are winning mama!!! Eventually she might start going back to bed but I’d argue that she might be more comfy on the floor if she seems to prefer it haha 🤣
Hello. My twins do the same thing. Sometimes one will be sleeping on the floor while other baby is on the bed. They are 16 months old but we’ve used a floor bed since they were 6 months old. They usually eventually move onto the bed. But if I can see they are safe and they don’t mind. I don’t see why not.
