Stomach aches and headaches and anxiety in kids:

When does anxiety in children become a medical concern?

You may notice that your child is a worrier. When you schedule a babysitter, your kid has prepared a list of interview questions to ask the sitter before being ok with it. When you're 5 minutes late to picking them up, they're in tears. They need to walk through any potential problems and come up with five solutions whenever faced with a new situation. You're happy to help! But when is it too much?

Anxiety is a concern when it gets in the way of "typical" functioning.

While some kids are more prone to worries than others, anxiety becomes a concern when it impacts their day-to-day functioning. So, instead of being in tears that you're five minutes late, they've had a huge blow-up and are waiting for you in the principal's office. Or, walking in to school on the first day, they're paralyzed and can't move from your side. They have trouble maintaining friendships. They consistently experience stomachaches and headaches, due to their ongoing stress.
