We can answer this question by “never”. Our brain is continually re-shaping itself to meet the demands of everyday life, even throughout our adulthood. As for brain size itself, it increases more gradually: your newborns’ brain is only about one-quarter the size of an adult’s. It grows to about 80% of its adult size by three years of age and 90% by five.
If your baby is eating a well-balanced diet rich in all kinds of fish, whole grain products, eggs and cereals, and drinking enough milk enriched with those 2 essential fatty acids, you don’t need to worry.
Not really. To be sure about your choice, all you have to do I read well the label on the tin.
It’s a real mistake to turn mealtimes into sparring matches to get him to eat a balanced diet. When he turns down the food you prepared, he’s not rejecting you, so do not take it personally. Besides, the harder you push him to eat, the less likely he is to comply. Instead, offer him a selection of nutritious foods at each sitting, and let him choose what he wants. Vary the tastes and consistencies as much as you can.
If he rejects everything, try to save the plate for later when he’s hungry. However, don’t allow him to fill up on cookies or sweets after he’s refused a meal since that will just fuel his interest in foods high in unnecessary calories (these foods are high in calories but low in important nutrients, such as vitamins and minerals) and diminish his appetite for nutritious ones. As hard as it may be to believe, your child’s diet will balance out over several days if you make a range of healthy foods and don’t pressure him to eat particular one at any given time.
