Is it normal for most requests to be met with a "No" or a "I don't want to"? Most of the time I can get him to comply but it is an uphill battle. For example "time for dinner" "let's go to the toilet" "let's brush teeth" are always a no. He obliges with things he wants to do and is usually fine to go out (except preschool).
He's 3.5yo.
Is this just par for the course for the age or do I need to worry?
