My daughter used to sleep around 10-10 30 at night and wake up by 8 30 -9 in the morning and sleep by 2 30 to 3 pm in the afternoon. But, now she sleeps by 11 - 12 at night and sleeps by 4 to 4 30 on the evening. she controls her sleep, and asks for my phone to play rhymes during bedtime which I never made a habit for putting her to sleep. entire day I tolerate her tantrum and onto this she does sleep on time. why is this happening?

A. for big children it is important to increase the physical activity of the child during the daytime and also see that the child is drinking plenty of water and is having a good diet just before sleep but at the same time the diet should be easily digestible and not very heavy diet which is causing more gas formation because that also can lead to digestion problem and that can dizsturb the sleep. also it is important to look for any environmental disturbance which is affecting the sleep like temperature variations as well as the mattress problem. rule out constipation which might be causing gastric disturbancez and change in sleep pattern
