My normally chill 2 1/2 year old has had several panicky sessions this week. Today, she had an inch worm on her in the car and was very scared by it. This afternoon, though there was no bug on her, she was screaming (really yelling) pretty steadily for about 30 minutes, clawing at her skin, shaking, totally panicked, thinking that there was another inchworm on her body. It took her about 1 1/2 hours to calm down, with repeated panicky sessions. She basically totally lost it and could not regain her composure for a very long time, though both my husband and I were right there and holding her. She wanted up to repeatedly rub her skin (arms, legs, feet, fingers, neck) with a wet wipe to make sure that no bug was on her skin.
This also happened one night this week when she had a dream about a bug. She wanted to stay perched on my stomach (or my husband's stomach) and would not touch the bed or the blanket. Again, it took about 1 1/2 hours for her to calm down and she was really shaking and crying.
Is this normal behavior for a 2 1/2 year old or not? (I'm concerned she may have more than usual anxiety, it runs in the family...)
