Do you think that is normal

It can be normal, depending on the situation. If they had just been scolded, or if their siblings were picking on them, or their friends were excluding them from a game.

I would simply tell him/her that you love him/her very very much and nothing will ever change that!

I don't find it completely out of the normal.

I wouldn't think so...my almost 5 year old asks daily if I still love her. Especially after being scolded.

I would say so. Obviously if it was true that there were no positive adults and relationships in his life there would be a problem, but 5 year olds can become very "woe is me" saying things like "nobody loves me", "I never get anything I want", "It's not fair", "Everyone hates me!" "I'm the only one that can't/doesn't get to ____!"

I think it is normal for the age to say this even when they have a very loving family. I however know a child that can tell you that she feels in her heart that her Mommy doesn't love her. I didn't even know how to respond b/c I have felt that the mother doesn't love the child since she was born. This parent is in LOVE with the idea of people thinking she is a parent, but doesn't actually want to be a parent.

You have to figure out if it's coming from something he heard on TV or in school. I would also sit him down and ask him why he said it. There has to be something going on and you need to figure it out.
