Am not belive for parents describing, they ar in sense to learn children to sleep in any situation.

 They are not interested  in loosing these pleasures. A habit to sleep in noise is manufacturing, but harmful. Today lots of noisy gadgets having, till music, videos, if music is silence, melodic calming and not affecting on children sleep. But better is mum s warm, lullaby songs, care and protect and close.

A not clear light at room, nothing worries him, distracts, tremble, irritates are OK. But external factors as irritated in sleep, that dulled, but not turned off for all, sleep is worry. A how much he sleeps, as a so he is sleep , that mum s worries in insufficient sleep norm. After if children wake up calmed, happy, thus he is individual needing in sleep is less, than norm. But if wake up, cries, caprice, thus sleep is bad organized, or unfavourable, or he is sicked. By experience, mum knows if he sleeps calm, as suddenly nervous, beat by legs, remove blanket, thus children is not OK. With sleep destroyers are beginning acute infection, and nerve psychical disease. Parents need to check a how his children sleeps, as not talking, crying in sleep, shaking, would not wake up from bed, and keep to sleep. If it's not case episode, but repeating appearance as for 2 months, thus visit psychoneurologist. Yes, we are seen our dreams, they are reflecting your day impressions, after a child hear terrible stories, saw movies, something feared, or wondered something at circus, that he will say thematic dreams.But, if the same terrible dream repeating, and very often, thus say it to the doctor, that with other symptoms,its a sing for nerve disease.
