My daughter will be 3 in April.. Well we have been told by all her therpapists(she is autistic) that she is the most anxious kid they have ever seen. Well it has come to out attention, that when something changes that she is not ready for or she gets upset or she goes somewhere new, she will become quiet and if you look at her eyes they are fully dialated.. She was at therapy the other day, the therapsit walked in the room and my daughter imediatly looked in her direction and her eyes dialated immediatly and she became stiff...Now she has been having tummy probs which lead to vomiting but only on the days she has gotten worked up... Is this anxiety?????
