My son is currently 18 months old. We have had our share of experiences with foods and food allergies with him. But we have also had the standard experience of his food tastes changing. When he was born there was breastfeeding, and then the migration to a bottle. Then later came the oatmeal and rice cereals, and the bottles of baby fruits. We our still working on switching from a bottle to a cup, and to get him to eat more solid foods. We can see that he knows what eating solid food is, he just has not yet chosen to eat solid foods.
