My daughter has just turned 5 and has started recently going into the kitchen cupboards when I'm busy elsewhere and helping herself to junk food. She's very slim and active and has 'treats' often. It's got to the point where I have stopped buying biscuits etc. We have resorted to putting locks on the kitchen cupboards and on the kitchen door but still sometimes my guard is down and she manages to get something. Today, we have been busy clearing space for the Christmas tree and general chores and she's had not one but two galaxy ripples.
I just cannot understand it - if she's hungry, she's given food. She has a very balanced diet. Why might this be happening and how do I tackle it?
