They can’t make choices. They want everything!
Chocolate or vanilla? Red shirt or yellow shirt? Play outside or read a book? Even adults can be indecisive, so you can imagine what a first grader is like. It can be almost impossible for a child this age to make a simple choice, even between options that are complete opposites.
What you should do: Don’t offer lots of choices all the time, but provide occasional opportunities for your child to make decisions.
