A. sleeping pattern in small children changes from time to time and there are various factors which might be playing in changing the sleep pattern Sleeping in children less than 6 months changes pattern from time to Sleeping pattern gradually improves with increasing age of the child. You have to take care of diet, thirst, environmental disturbances which might hamper the sleep of the child. Usually improves after 6 months of age but sometimes may improve only after 2 years of age. If growth of child is normal then also no need to worry about Kindly do not worry about sleep. It will gradually improve Also decrease any screen if going on. Some of the tricks you can use is 1. using swing or jhula 2. swaddling 3. soft music and lullaby 4. avoiding noise and light 5. burping regularly which will decrease stomach gas 6. walking softly with child on shoulder
