Taste and Smell
The taste and smell senses are very powerful and individual. What I might smell and taste and think is beautiful, another person can be repulsed by. Taste is detected in the mouth and smell through the nose.
However as we are realising the ears, nose and throat are all interconnected and have a big bearing on how each other works and functions. So any imbalance disruption could affect your sense of smell and or taste.
Often I hear friends with children with additional needs talking about how their children are fussy eaters and I imagine a part of that could be due to an impact on their taste and smell development. Sensations in the mouth can be heightened which can then have an impact on what is tolerable to eat.
Some children who have gross motor delays can also have muscular weaknesses around the mouth which can add to the difficulties in eating certain foods.
