At what age did you move baby in to their own room?

Sarah

My daughter is 9 months old and been sleeping in her own room since she Was 5 months. I was talking with a friend that has a 18 month old and was shocked I have my child in her own room she still sleeps with her child. I never even gave it a thought. Everyone's different but made me curious. When others transition their kids in their own rooms ✔
