3 year old and food

[Strawber]

I have 3 children. My middle child is 3 years old and I'm becoming worried by his appetite. I don't know if normal but he constantly asks for food, even when eating he is asking for more of something else. He begs for food all day long and goes into the fridge to demand food.

I'm completely fed up with the relentless asking, begging and crying despite getting plenty of food during the day. Is this abnormal what could it be.

First - is he a healthy weight full of energy ? If yes , you are doing fine. If he's lethargic, see a doctor, if he's overweight you need to be firmer and perhaps look at what he is eating

Second - is he bright ? Boredom ?

Or just thirsty

Have you done worms pills? They can infest for quite a long before the itchy bottom symptoms appear...
