Everyone has probably told their child to take a deep breath at some point in time but have you told your child why? Explain to your child that when she gets nervous before a test her brain is probably not getting enough oxygen because she is holding her breath without even realizing it! Make sure to explain that when her brain doesn’t get enough oxygen she can’t think clearly. Suggest to your child that she takes a couple of deep breaths before a test to get that oxygen flowing back to her brain.
