Hi Doctor, My child 3yr and 10months old and is very adamant and does not listen. he cries badly for 10 to 15 mins after his playtime with kids or when we ask him to switch off TV to name few examples. he used to confuse between I and you, here and there sort of words 2 to 3 months back and has just started using them right but still makes mistakes sometimes. he is active gets very excited. Also today is his 3rd day to preschool and the teacher told us he is not sitting in his chair and told that we can check for few days as he is new to classroom environment. Please let us know if it is point of concern. Regards , Parent
