While a child is learning to accept foods it helps if the parent understands that every change is a new experience for the baby and the baby may or may not be ready for that change.
By being aware the parent can see just what aspect of the food is not accepted and take a step back to progress according to what aspects of the food the child can manage and what new aspects may take more time. Eg when a new food is introduced the baby is coping with a different taste, texture, smell, thickness and maybe temperature.
The more a parent learns about eating development, watches what aspects of food matter to her infant, the more changes she will be able to make in the foods provided. This means more enjoyment at baby’s eating development and less frustration at not knowing what to do when baby hesitates with some new food.
