I believe that children should have healthy eating habits. I know with my two year old I like her to eat her dinner's, (not all but most of it) but how can I do that when her dad comes to visit, he is constantly allows her to snack, chocolate, lollies etc and when it comes to her eating dinner, she doesn't want it.

Then when he leaves its back to a normal routine (my routine..lol) and they still don't eat properly

What do you think???

Poor listening, or “noncompliance”, is one of the most common concerns expressed by parents of toddlers and school-aged children.Children love having fun; they want to keep doing it. Once a parent makes a request that ends or prevents fun, children may respond with behaviors ranging from whining to complaining to hurricane force tantrums. Sometimes, a parent can carry predictability and authority too far. Jumping right to punishment may cause the behaviors to decrease temporarily.
