Thank you for your query,
The developmental reorganization around 9 months of age in children, the development of separation anxiety
leads to further decrease in sleep duration in this age children.
Interacting with the kid in day time by play, engaging him in activity like in picture books and toys during day time will cut down his day sleep and he will sleep more in the night.
Introducing transitional objects like a favorite teddy bear or blanket may alleviate separation fear during night and there will be no frequent wake ups during night.
is safe but it should be used whenever there is a clinical indication but not exclusively for sedation.
Hope i have answered your query.
