I can't work this out! My 21 month old is lovely and well behaved (most of the time!) when my husband or I are looking after her separately but when we are home together on sat afternoons or Sundays she spends most of the time screaming, crying or throwing tantrums. For no real apparent reason. You would think having both parents around together would make her happy. I actually dread being home during these times. She is quite a spirited child and always has been. Is she confused, overwhelmed? Any one experience this?
