why my son keep forgetting things alot esp when he study

A. Hello good morning !! Observe kids grasping and concentration power,IQ levels. Generally kids concentrate for few minutes but they will have good grasping power ,encourage to learn ,concentrate well by teaching concepts activity,practical methods so that they will listen with interest and enthusiastic to learn/explore more. If you observe less IQ levels according to age then consult developmental paediatrician. Learning practical way,with concept base early morning ,pleasant environment will help him a lot. Encourage his small achievements to improve interest.
