Do noodles good for health below the age groups children of 3yrs ?

A three year old needs a balanced and varied diet with adequate amounts of carbohydrate, protein, fats, sugars, fibre and vitamins and minerals. Noodles are fairly nutritious if they are egg noodles - they contain protein and carbohydrate - but they should really be served with other things. In order to get the best from food, it should be chewed and mixed with saliva before being swallowed. I doubt that, at his age, your son has learned how to do that properly. Children of that age also very much enjoy fresh, raw fruit and vegetables (carrots, apples and whatever is available in your country). He should be encouraged to eat fresh fruit and vegetables which contain the right minerals and vitamins for his growth. You will have to prepare them in such a way, however, that he is not in danger of choking. Do use your doctor and also the internet to find out what makes a balanced and healthy diet for 2 to 3 year olds!

I do not see anything wrong with them eating that. I think at that age they are capable of digesting noodles. You could check with the professionals to know for sure, though.
