My son is 3 and generally behaves well. Sometimes he will make a fuss when he wants something we wouldn't give him but nothing exaggerated.
However he always cries when leaving nursery or a friend's house and the crying increased in the last few months. The other day he met a friend at the playground and when he left my son threw himself on the ground crying.
The thing starts to be embarrassing and I am also concerned there may be a problem with my son.
