Emotional 4 year old

[Loopyteddy]

Over the past few weeks my 4 year old DS has become extremely emotional when he is told off or someone says anything that he perceives as negative. It could be something as simple as asking him to put his coat on and pointing out I have already asked him 3 times.
He sobs, says he is worried I don't love him anymore and has started saying his heart is breaking into pieces.

I obviously reassure him that yes I do love him and always will then explain why I have said what I said and we will have a cuddle. However this is happening every time.

At my sister's recently she told my niece off and he was the same, even though he understood it was my niece who was being told off and not him. No amount of positive reassurance seems to help him.

Is this just normal for this age?

Has he just recently started school? My niece was exactly like this. Just cried alot x

@Couldntthinkofausername24 no he's in his second year at Pre-school

My 4 year old DD has started doing similar, very emotional & crying. If she thinks she's been told off or done something wrong she gets very upset. I've put it down to being extremely tired from school and the Christmas build up but I'm interested to see whether others have experienced this and possible reasons.

My 5 year old gets like this, asks if i still love her etc, she hates to think I'm upset with her.
She's worse when tired, like now after the last term at school. Currently having a nap which shows how tired she is as she never naps.

Perhaps it's just normal then?
It's really upsetting when he asks if I still love him. I give him lots of positive reassurance at other times and we always say that we love each other. Maybe he is just processing all the different emotions.
