A baby is more likely to accept a new food with its continuous exposition. If we expose a new flavor this many times (more if required) the baby’s palate will start to recognize the flavor and finally accept it (if they didn’t at first).
The majority of the time, an initial baby’s reaction is to make facial expressions that we tend to interpret them as the baby disliking the new flavor. However, it is simply their reaction to something unknown. As parents, we have to keep insisting and introducing the food (by itself, without mixing it, at least 9 times - in 9 different meals) to give them the opportunity to develop a taste for that new food. Some foods may take more than others.
As they grow, accepting new foods is harder than doing so from a younger age, so that’s why it’s also important to introduce all foods within the first 6 months of solids (from 6-12months). To also avoid picky eating later on.
👩🏻⚕️ All of this info comes from my pediatric nutritionist @dra.mafergastropedia who created an amazing solid introduction chart that balances the 5 nutrient categories in each meal, rotates all foods and introduces each new one more than 9 times (15 consecutive days, 3 times a day) for this reason mentioned and for potential allergic reactions, of course.
