Our 3 year old's bedroom is facing a street that has some low degree of traffic at night. There is a bus stop right under the window (we live on the 2nd floor), with buses going every 10 minutes until midnight and starting again around 5.30 am. Occasionally on Saturday nights some motorcycles would cause higher noise.
She moved to her own room about a year ago, and sleeps alone. We have never noticed that any of the car noise outside would disturb her sleep. We are nevertheless wondering if it can have any impact on the quality of her sleep in some ways that are not directly apparent. Does anyone know of any studies (on either children or adults) on this topic?
(Note: our own bedroom is on the opposite side of the apartment facing an inner garden, totally quiet. We cannot easily swap them because of their different sizes).
